The following items are known issues in TestStand 2017 SP1 sorted by Category.
| ID | Known Issue | |||||
|---|---|---|---|---|---|---|
| .NET Adapter | ||||||
| 139737 Return | Cannot create or edit code of a struct using the .NET Adapter You can use the .NET Adapter to call methods and properties of structs and classes. However, although you can use the .NET Adapter to create or edit code for a class, attempting to complete these operations for a struct results in an error. Workaround: N/A
| |||||
| 354252 Return | An error can occur when you simultaneously modify the invocations of multiple .NET code modules If you select two or more .NET steps that use the same assembly and class and you then modify the calls within the .NET Invocation control on the .NET Module tab, an error similar to the following error can occur: <strong><code>Array offset 2 is out of range; range is 0..1<br /> Error Code: -17324, Array index out of bounds</code></strong> This error is more likely to occur if the invocations of the two selected steps specify a different number of calls. Workaround: Modify the invocations of .NET steps individually.
| |||||
| 202206 Return | Error -17500 occurs when you execute .NET code modules that deserialize types Workaround: N/A
| |||||
| 402888 Return | When you access a .NET property in a child class that overrides set or get, only the override is available If you use a .NET Adapter step to access a property that overrides the set or get definition of the property in a base class, only the overridden method is available. For example, if you are overriding the set method of a virtual int defined in a parent class, the get method will not be available in TestStand if the child class is specified. Workaround: Specify the parent class instead of the child class in the Root Class control on the .NET Module tab to access the object. The .NET Adapter still uses the override in this case.
| |||||
| 406396 Return | Additional Results setting is not respected for elements of arrays within a .NET adapter step If you enable the option in the Log column of the Parameters Table for one or more individual elements of an array, the Log option for the array itself does not update accordingly. As a result, the array elements do not appear in the Additional Results panel and TestStand does not log them. Workaround: Enable the option in the Log column for the array itself instead of the individual elements.
| |||||
| 194456 Return | Attempting to debug .NET steps from a TestStand UI built with only native debugging results in vague error message If you are attempting to debug .NET code modules using the TestStand debugging features and you are using a TestStand User Interface built with native-only debugging (managed debugging disabled), TestStand returns the following vague error: <br><br>The Step Into operation failed for the following reason: 'Win32 error: 0x8971001e' <br><br>In this case, the code module executes correctly, but you cannot debug the code. <br><br>Note: This is expected behavior. The error does not correctly indicate what is causing debugging to fail. Workaround: Ensure that mixed-mode debugging is enabled for any TestStand User Interface in which you need to debug .NET steps to work around this issue.
| |||||
| 516361 Return | Expression error will occur when attempting to store a System.Object[] return value from a .NET code module into an array of 64-bit integers in TestStand. When a .NET code module returns an array of 64-bit numbers as a System.Object[] data type, specifying a TestStand variable which is an array of 64-bit integers in the parameter expression for the return value will result in an expression error during sequence analysis. Workaround: It is safe to ignore this error. The data is stored correctly in the TestStand array when the sequence is executed.
| |||||
| ActiveX/COM Adapter | ||||||
| 44060 4GQ7M6JO Return | Cannot specify an underlying data type when passing a variant parameter using the ActiveX/COM Adapter or API in expressions TestStand can call methods of an ActiveX Automation server with variant input parameters. However, some methods can fail if the underlying data type is not correct. The ActiveX/COM Adapter and API in expressions do not support specifying the underlying data type of variant parameters. When you use the ActiveX/COM Adapter to call a COM server method and pass a TestStand numeric value to an optional variant parameter, TestStand passes a variant of the VT_R8 data type to the COM server method. If the method expects a VT_I4 data type and the COM server does not handle the case of a different variant data type being passed in, you receive an error. Workaround: Create a wrapper VI or DLL that converts the variant data type appropriately and call the COM server method directly.
| |||||
| C/C++ DLL Adapter | ||||||
| 157130 Return | Verify Prototype option for the LabWindows/CVI and C/C++ DLL Adapters incorrectly includes the expression value in an array parameter prototype You can use the Verify Prototype option on the LabWindows/CVI and C/C++ DLL Module tabs to modify the prototype of a LabWindows/CVI or C/C++ function to match the parameter list you have specified. However, when creating an array parameter, the Verify Prototype option includes the size of the array, which is not necessary for a C/C++ parameter definition. This can lead to compile errors if you specify a non-constant array parameter size, such as using the GetNumElements() function. Workaround: Delete the incorrectly added text in the generated prototype.
| |||||
| 255602 Return | C/C++ DLL Adapter Create and Edit Code features return errors for functions that specify an array parameter The C/C++ DLL Adapter Create and Edit Code features return errors for functions that specify an array parameter. In the Create Code case, Visual Studio correctly launches and creates the new function, but TestStand is unable to find the function and returns an error. In the Edit Code case, TestStand returns an error. Workaround: You can ignore the error. In the Edit Code case, navigate to the function manually.
| |||||
| Database | ||||||
| 390817 Return | Filtering results fails for certain steps when using on-the-fly database logging If you specify a result filtering expression that includes only Passed and Done results, Wait and Sequence Call steps with a Failed result are not filtered. This behavior occurs only when using on-the-fly database logging. Workaround: N/A
| |||||
| 607873 Return | Database Viewer does not support viewing of an Oracle database through ODBC driver. When you use Database Viewer to access an Oracle database through an ODBC driver, it results in an error that states "ORA-01406: fetched column value was truncated". Workaround: Use an OLE DB provider to access the Oracle database, instead of an ODBC driver. Refer to the TestStand Help topic "Configuring Connection Strings" for examples of OLE DB connection strings and required Oracle client components for Oracle databases.
| |||||
| 607455 Return | Database logging hangs and eventually errors when connection string uses Microsoft Access 2016 (ACE.OLEDB.16.0) provider The error returned is -2147352567. Workaround: 1) For 32-bit TestStand, use the Microsoft Access JET provider. 2) For 32-bit or 64-bit TestStand, use the ACE.OLEDB.15.0 or ACE.OLEDB.12.0 provider (as long as ACE.OLEDB.16.0 is not installed).
| |||||
| 643628 Return | Attempting to log INF, NAN, or IND values to a Microsoft SQL Server database results in an error. Microsoft SQL Server FLOAT data type does NOT support storing +INF, -INF, NAN and IND as defined by IEEE 754. Workaround: Update your schema to use a precondition expression to not log a value for non-finite values.
| |||||
| 720987 Return | Error OUT or INOUT argument 1 for routine 'stored procedure name' is not a variable or NEW pseudo-variable in BEFORE trigger occurs when using a stored procedure with an Out parameter in a MySQL database This error occurs in custom schemas that use out parameters in stored procedures. This is a known MySQL bug: Out parameters error on second call when statement is a prepared statement. Note, the first stored procedure call will be successful, but the subsequent call will fail with this error. Workaround: N/A
| |||||
| 722820 Return | "Generate SQL" button of the Database Results Processor will output SQL of previous database connection string If the configuration of the database connection string is changed in the Database Results Processor, then the "Generate SQL" button is pressed, the SQL output will still be for the previous configuration of the database connection string. Workaround: Save changes to connection string and reopen dialog before using Generate SQL button.
| |||||
| File Differ | ||||||
| 425989 Return | File Diff/Merge Utility may report conflicts when subproperties are edited in one file and deleted in another If you use the File Diff/Merge Utility to compare two files, modify a subproperty in File 1, and delete the subproperty's parent property in File 2, the Merged File will display the parent property as deleted and report a conflict for the modified subproperty from File 1. You cannot directly right-click on the subproperty to resolve the conflict. Workaround: Use the right-click context menu options for the parent property to resolve the conflict.
| |||||
| 718635 Return | TestStand Diff and Merge Utility produces unreadable XML report when analyzing sequences with invalid characters The utility will produces an unreadable XML report when processing strings that contain characters outside of the XML valid character range, such as ASCII control characters. This can commonly occur in situations where raw data is stored in a string. Workaround: Remove invalid characters from the sequence.
| |||||
| IVI | ||||||
| 408196 Return | Installing a TestStand deployment does not report an error in some cases when importing an unsupported IVI configuration If you attempt to install a deployment importing an IVI configuration that requires the NI-DAQmx or NI Switch Executive drivers, TestStand does not return an error even though the import will not succeed. TestStand does return an error when other required drivers are missing. Workaround: N/A
| |||||
| LabVIEW | ||||||
| 49503 3ZCDRG77 Return | Cannot use LabVIEW RTE to load a VI without saving the library You cannot use the LabVIEW RTE to load a VI when you add the VI to the LabVIEW library without saving the library. Workaround: You must save the library first.
| |||||
| 50897 46PA3DMF Return | Help Topic menu item is disabled If a TestStand UI Control loses focus, the Help?Help Topic menu item is disabled in the TestStand LabVIEW User Interface. Workaround: If the Help?Help Topic menu item is disabled, click a TestStand UI Control to re-enable the menu item.
| |||||
| 51491 480JGC00 Return | LabVIEW user interface appears hung when Property Leak Report dialog box displays behind application The Debug Warnings dialog box is not modal and launches behind the LabVIEW Simple User Interface front panel when you exit the application and the process does not correctly release TestStand objects. Workaround: N/A
| |||||
| 136507 Return | You cannot toggle the Show VI Front Panel When Called option when the Run VI on Remote Computer option is enabled When you enable the Run VI on Remote Computer option in the LabVIEW Advanced Settings window in the sequence editor or in the Advanced Settings dialog box in a user interface for a LabVIEW step, you cannot enable or disable the Show VI Front Panel When Called option on the LabVIEW Module tab in the sequence editor or in the Edit LabVIEW VI Call dialog box in a user interface, even though the Show VI Front Panel When Called option retains the value that was set previously. However, regardless of the display, the front panel of a VI never displays on the remote computer. Workaround: You can ignore the setting of the Show VI Front Panel When Called option because the front panel never displays on the remote computer.
| |||||
| 153853 Return | Create VI button on the LabVIEW Module tab or the Edit LabVIEW VI Call dialog box does not create a VI in an LLB When specifying a LabVIEW code module, you can create a VI by clicking the Create VI button on the LabVIEW Module tab or the Edit LabVIEW VI Call dialog box. However, you cannot create a VI directly in an LLB, and attempting to do so returns the error '"newfilename" File not found in LLB, Please verify the correct file name was given.' Workaround: Create the VI outside of the LLB, resave the VI in the LLB using LabVIEW, and update the path to the VI in TestStand.
| |||||
| 161523 Return | Arrays passed from LabVIEW to TestStand are transposed When a VI connector pane passes an array from LabVIEW to TestStand, the array is transposed. For example, a 2D array of four columns and five rows from a LabVIEW VI appears as an array of five rows and four columns when stored in a TestStand PropertyObject. Workaround: Pass the array back to LabVIEW, and the opposite transformation occurs to restore the original position of the elements.
| |||||
| 184366 Return | Clicking the Create Custom Data Type button on the LabVIEW Module tab for a cluster that contains unknown types results in an error When you click the Create Custom Data Type button on the LabVIEW Module tab to create a custom data type for a cluster that contains unknown types, such as 64-bit integers, TestStand returns the following error: "Bad object type passed Error Code: -17001, Program Error." Workaround: N/A
| |||||
| 188059 Return | The LabVIEWModule.ExpressVIName property does not update to match the Express VI title when a different configuration changes the title When you browse to and select an Express VI to load, TestStand launches the Express VI configuration dialog box. Some Express VIs modify the title of the VI based on the current configuration settings. TestStand does not update the LabVIEWModule.ExpressVIName property to match the modified Express VI title once you configure the Express VI. Workaround: N/A
| |||||
| 245655 Return | Cannot call VIs from LabVIEW packed project libraries when the full path of the VI is longer than the maximum path length When you configure TestStand to call a VI from a LabVIEW packed project library and the full path of the VI is longer than the maximum path length, TestStand does not find the file or reports that the VI is an unexpected type. Workaround: Ensure that the full path of the VI you call is shorter than the maximum path length.
| |||||
| 254553 Return | TestStand might become unresponsive while LabVIEW launches a prompt to save a VI If you attempt to create or edit a VI from TestStand while the LabVIEW Development Environment launches a prompt to save a VI, TestStand might become unresponsive. Workaround: Close the LabVIEW dialog box to make TestStand responsive again.
| |||||
| 279822 Return | TestStand appears to hang when LabVIEW search dialog box does not come to front when browsing for a VI that is missing subVIs The LabVIEW search dialog box is not modal to a TestStand User Interface, so When you browse for a VI that is missing one or more subVIs, a maximized TestStand User Interface hides the LabVIEW search dialog box, and it appears that TestStand has hung and become unresponsive. Workaround: Minimize the TestStand User Interface window or make LabVIEW active to bring the LabVIEW search dialog box or open file dialog box to the front.
| |||||
| 303452 Return | Logging reference parameters in a LabVIEW step can cause an error If you call a LabVIEW code module that meets all of the following conditions, TestStand returns the <strong><code>Type of argument expression is incompatible with parameter. Expected Number, found Object Reference. [Error Code: -17313, Could not accept the parameter passed in.]</code></strong> error when the step executes: <ul> <li>The code module contains a reference parameter that is represented as a numeric (such as a VI refnum).</li> <li>You enable the Log option in the Parameters Table for the parameter.</li> <li>You do not specify a value for the parameter.</li> </ul> Workaround: Specify a value or disable logging for the parameters.
| |||||
| 390139 Return | VIs in a LabVIEW project saved in the instr.lib directory fail to load when you configure the LabVIEW Adapter to use the LabVIEW Run-Time Engine Calling a VI code module returns a <strong><code>File Not Found</code></strong> error when all of the following conditions are true: <ul><li>A LabVIEW project contains the VI and a TestStand step specifies the project</li> <li>The LabVIEW project file is saved in the <code>instr.lib</code> or <code>vi.lib</code> directory</li> <li>You configure the LabVIEW Adapter to use the LabVIEW Run-Time Engine</li></ul> This error occurs because TestStand incorrectly generates the VI file path by replacing <code>LabVIEW\</code> with <code>TestStand\bin\</code>. This issue does not occur on a deployment target computer because the TestStand Deployment Utility moves the dependencies to a different location that does not experience this issue. Workaround: Call the VI directly and do not specify a project path.
| |||||
| 397556 Return | Keyboard entry is ignored when editing a code module from User Interface run in LabVIEW When you use a TestStand User Interface run in LabVIEW and you click the <strong>Edit VI</strong> button on the Module tab to edit a VI code module, you cannot use the keyboard when editing the code module. You can successfully initiate the operation to Edit Vi when running the TestStand User Interface as an executable. Workaround: Open and edit the VI directly in LabVIEW. Do not use the Edit VI button to open the VI.
| |||||
| 444028 Return | LabVIEW code modules that use an identical name for a control and an indicator may cause unexpected behavior when used in a LabVIEW step If you create a LabVIEW VI where a control and an indicator use the same name (for example, a control and an indicator both named "Numeric"), unexpected behavior may occur when you use that VI in a LabVIEW step. This behavior could include errors in the parameter list or a message stating that the parameter list does not match the VI prototype. In some cases, the behavior may change when you save and re-open the sequence file. Workaround: National Instruments recommends that you rename controls and indicators in the VI so that no duplicate names exist.
| |||||
| 478779 Return | An error may result when multiple threads access and save a LabVIEW class reference stored in a StationGlobal or shared FileGlobal variable When multiple threads access a LabVIEW class reference from a shared variable, such as a StationGlobal, and save the class reference back to the variable after a Class Member Call, an error may occur due to a race condition. This error occurs because the LabVIEW class reference may change during the Class Member Call, causing the previous class reference to be released. This outcome can result in other threads attempting to access a LabVIEW class reference that no longer exists. A -18001 error code is most commonly seen with this issue, but other error codes may also appear. Workaround: Use one of the following workarounds to resolve this issue: <ul> <li>Use local variables to store LabVIEW class references.</li> <li>Do not save the LabVIEW class reference back to a shared variable after a Class Member Call step.</li> </ul>
| |||||
| 484775 Return | -A -18002 type mismatch error may occur on a LabVIEW adapter step with parameters set to use a default value when the RunState.Execution.SetSequenceDefaultValues() TestStand API method is used in the execution. When a LabVIEW code module is dynamically loaded but not dynamically unloaded and the RunState.Execution.SetSequenceDefaultValues() method is used to set default values for the sequence, the -18002 error will occur if the parameters for the LabVIEW code module are configured to pass a default value to the code module. This issue usually occurs when restarting an execution after a previous execution completes. Workaround: Configure the LabVIEW adapter step to unload after the step executes. Additionally, you can prevent this issue from occurring by not restarting a completed execution.
| |||||
| 493571 Return | LabVIEW code modules with a NI VeriStand .NET type definition reference as a VI parameter will fail to load in TestStand when the LabVIEW Development System is active. This issue only occurs when using the Workspace Manager or Project reference from the NI VeriStand API. These references are .NET objects type definitions in LabVIEW. Workaround: There are two ways to prevent this issue from occurring: <ul> <li>Configure the LabVIEW adapter or the step to use the LabVIEW Runtime rather than the LabVIEW Development System.</li> <li>In LabVIEW, disconnect the .NET reference from the LabVIEW type definition.</li> </ul>
| |||||
| 544646 Return | Error -17313 or -18005 occurs when passing a .NET refnum constant in a cluster from newer versions of LabVIEW into TestStand If a LabVIEW VI with a cluster that contains a .NET refnum is passed into TestStand, then error -17313 or -18005 may occur. An example of this type of refnum would be when you create a constant from a .NET terminal in LabVIEW. Workaround: Construct the .NET object from a constructor node in LabVIEW, bundle it into a cluster, and pass that cluster out of LabVIEW.
| |||||
| 547957 Return | LabVIEW "key down?" event is not triggered when using the space or enter keys for TestStand ActiveX button controls LabVIEW UI event structures do not trigger a "key down?" or "key down" event on TestStand ActiveX Buttons, but other keystrokes do fire an event. Workaround: Use a LabVIEW button and bind it to TestStand functionality.
| |||||
| 555104 Return | Error -18005 occurs when passing a LabVIEW "Not a Path" constant from TestStand into LabVIEW Passing a "Not a Path" constant from LabVIEW to TestStand and then passing that constant back from TestStand to LabVIEW in the LabVIEW RTE results in the following error: -18005; Failed to convert a TestStand type to a LabVIEW type or vice versa. Workaround: Use an empty string instead of the "Not a Path" constant.
| |||||
| 566400 Return | LabVIEW VI absolute path check does not handle PPLs properly At load time, when the LabVIEW Adapter checks VI paths to make sure they are not pointing to two different copies of VIs with the same name, the code does not properly account for PPLs. If two steps reference a VI with the same name in the same PPL located in different places on disk, the first VI loaded should be used for both VI calls. However, because the function that checks the VI paths does not correctly handle PPLs, an error is generated. Workaround: Ensure that you only include and invoke one copy of the PPL in your test system. Alternatively, to prevent the error from occurring, you can manually load the PPL from the location on disk that you want to use. You can do this either by calling a dummy VI in the PPL or by using Open VI Reference in a user interface and then leaking the reference.
| |||||
| 632567 Return | LabVIEW operator interfaces built in LabVIEW 2016 might be slow to exit When you exit a LabVIEW operator interface built in LabVIEW 2016, the operator interface might be slow when exiting the process. Workaround: Rebuild the operator interface in LabVIEW 2015 SP1 or earlier.
| |||||
| 658319 Return | Connector panes that reference large LabVIEW class hierarchies reload the entire hierarchy when selecting a step. If a LabVIEW step references a VI whose connector panes uses data value references or directly uses a large LabVIEW class, the TestStand Sequence Editor reloads the step and all of its dependencies each time the step is selected. Workaround: In the sequence file properties, set the Load Option to Preload when opening sequence file.
| |||||
| 716835 Return | Time Stamp conversion fails intermittently when value passes between TestStand and LabVIEW At random times when Time Stamps are passed back and forth between TestStand and LabVIEW, TestStand sends a Time Stamp string with a resolution of 0.0001 seconds instead of 0.001 seconds. This causes LabVIEW to dafault to an emtpy "00:00:00.000 PM MM/DD/YYYY" Time Stamp. Workaround: Add error checking code in TestStand to make sure the Time Stamp string has a correct format before passing it to LabVIEW.
| |||||
| LabVIEW NXG | ||||||
| 664496 Return | Selecting a file path longer than 256 characters in the LabVIEW NXG Adapter will cause unexpected behavior. N/A Workaround: Do not use a file path longer than 256 characters.
| |||||
| 658107 Return | Invalid paths for non-LabVIEW steps do not migrate properly when using the TestStand LabVIEW NXG Conversion Utility. If a step that does not use the LabVIEW adapter contains an invalid path in the original sequence file, the converted file will contain an empty string for the path. Additionally, absolute paths for the PropertyLoader steps will be unchanged by the conversion utility, instead of updating to a new absolute path to the converted output. Workaround: N/A
| |||||
| 662205 Return | Unable to update existing type definition for an array of clusters containing an enum from a LabVIEW NXG code module. The Create/Update Custom Data Type dialog box's option to "Update an Existing Type" will not update the TestStand type definition from LabVIEW NXG if the type has an array of clusters that contains an enum. After pressing the "Update an Existing Type" button you will see that no changes to the TestStand type definition were made. Workaround: You can manually update the TestStand type definition, or delete the existing type and create a new type definition in TestStand.
| |||||
| 669606 Return | Analog Waveform variables that contain attributes generate a run-time error when passed to LabVIEW NXG. If a local variable of an Analog Waveform is passed to a LabVIEW NXG code module and has one or more attributes, then a run-time error is generated when executing the step in the LabVIEW NXG Development Environment. The error will not occur when executing with the LabVIEW NXG Run-Time Engine. Workaround: Set adapter configuration to use LabVIEW NXG Run-Time Engine.
| |||||
| 669830 Return | The "Undock Labview NXG Help" button is missing from User Interfaces when they are in editor mode. In the step settings pane of a LabVIEW NXG step, the "Undock LabVIEW NXG Help" button is missing in a User Interface when it is in editor mode. Workaround: N/A
| |||||
| 671819 Return | When overwriting a LabVIEW NXG Project through TestStand, a new instance of LabVIEW NXG is launched with the same project name while the original project is still loaded in the first LabVIEW NXG instance. When using the "Create New LabVIEW NXG Project..." option to overwrite an existing project, TestStand launches a second instance of LabVIEW NXG with the same name instead of replacing the existing LabVIEW NXG instance. Workaround: Close the first instance of the LabVIEW NXG project or use LabVIEW NXG to overwrite a project.
| |||||
| 675567 Return | LabVIEW NXG does not support a container with an array element of containers. If a parameter for a LabVIEW NXG VI is a container with an element that is an array of containers, the step will not be configurable and will result in a compatibility error. Workaround: N/A
| |||||
| 675658 Return | The Conversion Utility reports "Conversion of Files Completed", when no files have been converted. If the user has read-only access to the output directory, the conversion utility will report "Conversion of Files Completed", but will also report the error "failed to copy files to target location". Workaround: Use a directory with write access.
| |||||
| 683498 Return | Common Parameters are Disabled When Selecting Multiple LabVIEW NXG Steps When selecting multiple LabVIEW NXG steps to edit common properties, all properties will be disabled rendering them unable to be edited. Workaround: Edit step properties individually.
| |||||
| 684110 Return | Clicking on the filter icon for the file column in the log window of the TestStand LabVIEW NXG Conversion Utility throws an exception. When pressing the filter icon button in the TestStand LabVIEW NXG Conversion Utility, the exception "Object reference not set to an instance of an object." occurs. Workaround: N/A
| |||||
| LabWindows/CVI | ||||||
| 381096 Return | Additional results logging setting for parameters in LabWindows/CVI or C/C++ DLL steps update incorrectly when you change how the parameter is passed If you configure a parameter in a LabWindows/CVI or C/C++ DLL step to be passed by reference and then you enable the Log option in the Parameters Table, TestStand logs both the In and Out values of the parameter. You can configure the logging of the In and Out data independently on the Additional Results panel of the Properties tab of the Step Settings pane. If you later change the parameter settings such that it is passed by value, then execute the sequence, you will encounter an error similar to the following: Details: The following error occurred while logging additional result 'x [Out]': Array offset -1 is out of range; range is 0..0.. Error in parameter 1, 'x'. Error Code: -17324; Array index out of bounds. This error occurs because the the log setting for the "Out" value is still enabled, despite the fact that it is no longer a valid option. Workaround: To disable logging for the Out value and prevent the error, you must configure the parameter so it is passed by reference so that the Out logging option is available. After disabling the option, set the parameter back to being passed by value.
| |||||
| 413438 Return | LabWindows/CVI Adapter does not recognize object array or void* parameter types with fixed array size If you load a LabWindows/CVI 2013 or later built DLL code module that uses object array or void* parameter types with fixed array size, TestStand returns a warning to indicate that the prototype of the function cannot be read. Workaround: Manually configure the prototype on the Module tab or change the prototype in the code module to avoid object array or void* parameter types with fixed array size to work around this issue.
| |||||
| Microsoft Visual Studio | ||||||
| 109366 Return | Calling a .NET module as an OnNewStep custom substep can error TestStand returns an error when calling an OnNewStep custom substep that calls a .NET WinForm that requires an STA thread. Workaround: N/A
| |||||
| 127991 Return | Receiving UI events in a .NET class that is not created in the UI thread might cause errors Registering a .NET class to receive UI events from a TestStand UI Control, such as the Application Manager control, can cause unexpected re-entrancy issues when the .NET class is not created in the UI thread. Workaround: N/A
| |||||
| 51321 47JBHTIA Return | MFC-based TestStand User Interfaces can crash when used with the Microsoft Team Foundation Server SCC provider TestStand User Interfaces based on the Microsoft Foundation Class (MFC) might crash when you use the Workspace Browser dialog box with the Microsoft Team Foundation Server SCC provider. Workaround: Programmatically install a different message filter. Contact NI Support for more information.
| |||||

| TestStand Deployment Utility | ||||||
| 152924 Return | Deploying files after moving a .tsd file and unchecking files for deployment might change the deployment destination directories or truncate filenames If you change the directory in which a deployment .tsd file resides and you unchecked files from being deployed after saving the .tsd file, the TestStand Deployment Utility might display truncated filenames after analyzing the files. When building, the TestStand Deployment Utility might also change the structure of the destination files, so that the structure is different compared to the structure that existed before you moved the .tsd file. Workaround: Keep the .tsd file in the same directory in which it was created or leave at least one file checked in the topmost directory to prevent the algorithm that determines the destination directory structure from returning a different result.
| |||||
| 182127 Return | The TestStand Deployment Utility assigns the same default destination directory for two files with the same filename and file hierarchy but located on different drives If a workspace contains two files with the same filename and file hierarchy on two separate drives (for example, C:\ and D:\), by default the TestStand Deployment Utility assigns the same destination directory for both files, which results in an "Error: The following files have conflicting destinations:" build error. Workaround: Manually modify the destination directory for one of the files.
| |||||
| 191976 Return | TestStand Deployment Utility does not properly update TestStand Deployment (TSD) file paths that contain user names when you move the files and a different user loads the TSD file If file paths of a TestStand Deployment (TSD) file, such as the Workspace File Path, contain a user name (User A's Desktop) and you move the files to a path that does not contain the user name (C:\), when a different user loads the TSD file, the TestStand Deployment Utility incorrectly updates the file paths to point to the previous path using the new user name (User B's Desktop) instead of pointing to the correct path (C:\). Workaround: Do not store the files in paths that contain user names, such as Desktop or My Documents. Alternatively, when you move the files from a path that contains user names to a path that does not contain user names, load the TSD file with the same user to correctly update the paths.
| |||||
| 192254 Return | Destination directories for files you do not select in the TestStand Deployment Utility may appear distorted when you convert TestStand Deployment files from an older version of TestStand to a newer version When you load a TestStand Deployment file that was saved in a previous version of TestStand into the TestStand Deployment Utility, the destination directories on the Distributed Files tab may appear distorted for files that you have not selected. Workaround: Select and then revert the selection for the file to update the Distributed Files tab with the correct destination directory but leave the file excluded from the deployment.
| |||||
| 252650 Return | TestStand Deployment Utility does not update the workspace path if you save the deployment and workspace files to the desktop then move the files When you save workspace and deployment files on the desktop, move the files to a new location, and then load the deployment file in the TestStand Deployment Utility, the Workspace Path control expects the workspace file to be located in the Desktop directory. Workaround: Browse to the new workspace file location.
| |||||
| 249171 Return | A warning can occur when you build a deployment that includes VIs that contain unsupported Microsoft Windows characters If a deployment contains VIs that use characters that are not valid for Microsoft Windows files, such as the slash (<code>/</code>) or question mark (<code>?</code>) character, and you enable the <strong>Output VIs to Packed Project Library</strong> option in the LabVIEW VI Options dialog box, the TestStand Deployment Utility returns a warning similar to the following warning when building the deployment: <strong><code>Warning: Cannot update VI Path: Step '<stepName>', sequence '<sequenceName>', sequence file '<sequenceFilePath>'</code></strong> If you install the deployment on a target computer, the step the warning references does not not execute. This issue occurs because the paths for VIs contained within a packed project library must use only valid Windows filename characters, which is not the case for VIs within LLBs or LabVIEW libraries. Workaround: Use only valid Windows filename characters when naming VIs and virtual folders.
| |||||
| 678105 Return | The TestStand Deployment Utility returns the error -19062 when deploying components to a local repository or package installer. If the "NI Certificates Installer" package is not installed on the system, and NI Package Manager cannot locate the package on one of its feeds, when the TestStand Deployment Utility attempts to include NI Certificates package in the distribution, the build returns "error -19062: Could not calculate EULA dependencies". Workaround: You can do one of the following: 1) Open NI Package Manager after installation which will register the required feeds with ni.com. 2) Manually install the "NI Certificates Packages" on the system 3) Disable the option "Include NI Certificates Package" on the Configure Package Attributes dialog.
| |||||
| 711553 Return | Changing base destination of a packed project library in the TestStand Deployment Utility causes the build to fail When building a packed project library with the Deployment Utility, you can select the .lvlibp item in the distributed files tab and change the base destination of the library. If you do so, the VIs in the library are incorrectly configured to have a destination subdirectory which matches the library name. This invalid setting causes the build to fail. Workaround: To fix the error, the setting to build a packed project library must be disabled, remove the folder destination from the files, then re-enable the setting. You can successfully change the library destination by configuring the base destination of VIs within the library individually, or by changing the base destination of a parent directory of the library.
| |||||
| TestStand Engine | ||||||
| 135202 Return | TestStand returns the error "The TestStand service did not start up promptly" when you launch the sequence editor or a user interface When the TestStand Engine is created, the engine checks with the National Instruments TestStand Service to ensure that external environments such as LabVIEW, LabWindows/CVI, and Microsoft Visual Studio are properly updated. If the service is not available, TestStand returns the error "The TestStand service did not start up promptly." The TestStand Service is required for this external environment setup to allow non-administrator users to properly configure these environments. The TestStand Service can sometimes be delayed while launching because a previous service hangs when starting. For example, the Windows Workstation service might hang for a few minutes on startup when trying to reconnect to mapped network drives if the drives are not immediately available. This can cause the TestStand Service to be unable to start, and if a TestStand User Interface is launched before the service starts, TestStand returns this error. Workaround: Generally, you dismiss the error dialog box and continue to use TestStand normally, as long as you do not require the external environments to be configured. To remove the error, try to determine the offending service that is delaying the TestStand Service from starting, and see if you can correct the source of the slow start. You can also delay the launching of the offending service by marking the service as manual startup, and adding a command to the startup group to start the service after other services have been started.

| 144062 Return | Calling the Module.CreateCode or Step.CreateCode methods on a .NET step or module returns an error if the methods are called from a non-STA thread The Module.CreateCode and Step.CreateCode methods must be called from a Single Threaded Apartment (STA) thread if you are trying to create .NET code. If you do not call these methods from an STA thread, TestStand returns the following error: "Error -18500: An error occurred during Visual Studio automation: The message filter indicated that the application is busy." Workaround: Most development environments initialize a UI thread to be an STA thread, so calling these methods from the UI thread is usually safe. Otherwise, you must manually initialize a thread to be STA, and the procedure differs with each environment.

When you enable this option and you close the workspace file while sequence files are currently loaded, a dialog box prompts you to close all opened document windows. If you click Yes in this dialog box, all loaded sequence files close along with the workspace file. When you reopen the workspace file, the previously loaded sequence files do not reload. If you click No in the dialog box or if you exit TestStand, the previously loaded sequence files reload when you reopen the workspace file. Workaround: N/A

| 185097 Return | Configuring a SequenceCall step to launch a new execution from within the SequenceFileLoad Engine Callback hangs the SequenceFileLoad execution when you load the sequence file If the SequenceFileLoad Engine Callback contains a SequenceCall step configured to launch a new execution, when you load the sequence file and the SequenceCall step executes, the SequenceFileLoad execution hangs until you manually terminate it. This behavior exists only when you load the sequence file. Running the SequenceFileLoad sequence manually executes properly. Workaround: Configure the SequenceCall step to launch a new thread instead of a new execution or use the TestStand API Engine.NewExecution method to programmatically launch a new execution.
| |||||
| 232693 Return | Batch synchronization behaves incorrectly when you set a SequenceCall step and the steps within the subsequence to serial batch synchronization When you configure a SequenceCall step for serial batch synchronization and also configure the steps of the subsequence for serial batch synchronization, the execution behaves unexpectedly when the steps the subsequence calls include a For Loop. Workaround: Configure batch synchronization only for the SequenceCall step or only for the steps the subsequence calls. Do not configure batch synchronization for both.

| 509895 Return | A type conflict dialog box generates when a file is loaded which contains a modified version of CommonResults or NI_UserCustomPrivileges types. This issue occurs when the first file which uses one of the modified types is loaded, and occurs even if the Allow Automatic Type Resolution station option is set to Never. Workaround: Complete either of the following steps to workaround this issue: <ul> <li>Avoid modifying the CommonResults or NI_UserCustomPrivilege types.</li> <li>Avoid using the Never option for the Allow Automatic Type Resolution station option. The Only if Type Palette file has the Higher Version option will not automatically resolve conflicts between two sequence files unless the type is also stored in a type palette file.</li> </ul>
| |||||
| 51517 47SGL33Q Return | Passing the FileGlobals PropertyObject as a parameter to a subsequence in the Batch process model will cause a PropertyObject leak warning dialog to appear when the TestStand Engine is shut down. This issue only occurs if the entire FileGlobals container is passed as a parameter into a subsequence, such as Single Pass -- Test Socket Entry Point. Workaround: Create a container within the FileGlobals container to hold the properties you wish to pass into the subsequence, and pass this container instead of the top-level FileGlobals container.
| |||||
| 722577 Return | Random function in TestStand expressions can return the same value if re-seeded on every call When looping over the Random() function in a TestStand expression, if the random value is re-seeded on every call to the function over time it can return the same value on repeated calls. In general, re-seeding a pseudo-random number generator is something that should be done once, or at least rarely, for the lifetime of the use of that generator because it resets the pseudo-random number distribution. Workaround: Only re-seed the number once, not on every call.

| 137446 Return | Double-clicking a Sequence Call step that calls a sequence in a new file does not scroll the Sequences pane if the new sequence file is not already open Double-clicking a correctly specified Sequence Call step opens the sequence being called and highlights the sequence on the Sequences pane. However, if the sequence file being called is not already open, the sequence is highlighted on the Sequences pane, but the Sequences pane does not scroll so that the selected sequence is visible. Workaround: Scroll the Sequences pane to view the selected sequence.
| |||||
| 139956 Return | TestStand User Interfaces do not reload a process model if it is modified on disk while loaded into memory If the sequence editor or a user interface loads a process model into memory and the process model then changes on disk, the sequence editor or user interface does not automatically reload the process model. This issue occurs because loading a sequence file automatically loads the associated process model, and the process model can be modified on disk by a Source Code Control (SCC) system or by another TestStand process. Workaround: Select File?Unload All Modules or manually open the process model file from disk to force a reload of the process model.

| 51939 49O5JI9Q Return | TestStand Sequence Editor seems to hang when launching the Customize Toolbar dialog box after changing the number of monitors in the system The Customize Toolbar dialog box is a modal dialog box. If you configured a system to use multiple monitors, opened the Customize Toolbar dialog box, then moved the dialog box to a secondary monitor screen before closing the dialog box, when you remove the additional monitor(s) from the system, the TestStand Sequence Editor appears to hang the next time the Customize Toolbar dialog box launches. This occurs because the Customize Toolbar dialog box tries to display on a monitor that no longer exists in the system. Workaround: If you experience this apparent hang, press the <Enter> key to close the modal Customize Toolbar dialog box. Configure the system to use multiple monitors, launch the Customize Toolbar dialog box, move the dialog box to the primary monitor, and then close the dialog box. If you remove the additional monitor(s) from the system, subsequent launches of the Customize Toolbar dialog box display the dialog box on the primary monitor.

| |||||
| 535022 Return | Editing a localized expression in the Variables View does not properly unlocalize the expression before storing the value back into the variable. For example, editing an expression in the Variables View that is localized to use commas as decimal points will lead lead to unexpected token errors when the commas are stored instead of periods. Workaround: Do not use the Variables View to edit expression values when using localized OS and TestStand settings, or turn off the localized decimal point option in OS or TestStand.
| |||||
| 615962 Return | Limits for Numeric Limit Test and Multiple Numeric Limit Test steps do not show EQT comparison options when the comparison type is specified by an expression or when you are editing multiple steps If the comparison type is specified by an expression or if you have selected more than one of these steps, the Limits tab options display only the non-EQT comparison types, which do not show Threshold Type and Nominal Value.
