The following items are known issues in LabVIEW NXG 3.1 sorted by Category.
| ID | Known Issue | |||||
|---|---|---|---|---|---|---|
| Controls and Indicators | ||||||
| 249396 Return | Cursors added to graph in Operate mode do not appear in Edit mode When you add a cursor to the graph through the legend while the VI is in Operate mode or while the VI is running, then that cursor will now show up in the graph or in the legend, when the VI is returned to 'Edit' mode. Workaround: Add all expected cursors for the graph when the VI is in Edit mode.

| 482816 Return | Selection in Array of Clusters of Arrays constant loses focus. Selecting an array inside a cluster inside another array loses focus when hovering over another element of the top array. This makes it difficult to edit the items in the inner-most array. Workaround: N/A
| |||||
| 630075 Return | IO constants cannot be resized when contained within a cluster connected to a G Type. IO constants can be resized manually when contained within a cluster constant. However, IO constants cannot be resized once the containing cluster is connected to a G Type. The IO control in the G Type can be resized but this change is not reflected in any connected constants. Workaround: Disconnect the cluster from the G Type, resize the IO constant, and then reconnect to the G Type.

| 605135 Return | Some strings remain in English rather than localized language when converted to LabVIEW NXG When setting a localized dictionary and converting from LabVIEW to LabVIEW NXG, some strings may remain in English. Specifically, strings that are labels instead of captions will appear in English Workaround: Set a caption for controls prior to conversion or update text after conversion

| 514789 Return | Autotuning PID Online.VI Example Reads Proportional Gain 'NaN' with the Relay Technique. When running the Autotuning PID Online.vi example, with the Relay Technique the "Tuned PID gains" output of proportional gain (Kc) shows "NaN" when the program believes tuning is completed by flashing "tuning completed?". Workaround: Tune the individual terms first. Start by first tuning for P until the response is stable. Then continue to tune by switching to PI. Lastly, repeat the process for PID.

| 599434 Return | Dynamic dispatch controls are not supported inside structures Placing a dynamic dispatch control inside of a structure provides the following error: The run-time type is not propagated from dynamic dispatch input to dynamic dispatch output. You must ensure that there is a wire path that flows to all dynamic dispatch indicators. Workaround: Remove the control from the structure and the error will clear.

| LabVIEW Project | ||||||
| 599881 Return | Empty folders in project don't show up in the files pane when opening a project When you open a project with empty folders, those don't show up in the files pane. Workaround: N/A
| |||||
| Menus | ||||||
| 644397 Return | Workbooks do not restore maximized after minimizing the environment window with a maximized workbook open. A maximized workbook window will minimize when the environment window is minimized. Restoring the environment window will also restore the workbook window but not in the maximized view. Workaround: Maximize the workbook window manually after restoring the environment window.
| |||||
| 643608 Return | Right clicking on a tunnel of queue of numeric type shows the numeric palette For most data types, the right click menu from the queue terminals shows the palette queue. Right clicking on a tunnel of numeric type shows the numeric palette. Workaround: Manually drop from the queue palette instead of right-clicking.
| |||||
| Miscellaneous | ||||||
| 584767 Return | Some UI elements in the environment may not display correctly using custom DPI settings. Some UI elements may display incompletely if using a custom Windows DPI setting of 125%, or similar. Workaround: Use default DPI settings.
| |||||
| 660805 Return | Windows "line per notch" scroll wheel settings do not apply to NXG The scroll wheel movement amount does correlate to the scroll size defined in the Windows mouse settings. For example there's no difference in the amount of block diagram scrolled whether the set to 1 line per notch or 10 lines per notch. Workaround: N/A
| |||||
| 662414 Return | Error & Warnings Panel continuously expands and collapses after repeated pinning and unpinning Normally, The Error & Warnings panel pops up when the mouse is hovered over it. In some cases, the Errors and Warnings window may expand and collapsed continuously after pinning and unpinning the Errors and Warnings panel. Workaround: Click the tab.
| |||||
| 678830 Return | Dictionaries are only found in specific language culture Parent cultures will not find the dictionary even if the language matches the parent culture. As a result, localization will not happen. Workaround: Place the dictionary into a language-specific folder, e.g. de-DE, de-CH, de-LI, etc
| |||||
| Upgrade - Migration | ||||||
| 641719 Return | Projects with large file hierarchy error out during conversion with unclear error message The conversion tool adds hierarchy to the project structure during conversion that extends the length of the file path. As a result, file paths can become too long for Windows and create a situation where the conversion utility cannot find files at paths that do not exist. This will result in the following error: Conversion could not find this file at specified path The reason for the file not found is not clear in the action being made. Workaround: Make shorter file paths initially so the added hierarchy doesn't extend beyond Windows file path limits
| |||||
| 682314 Return | Interop node claim VI is invalid if containing Python node Interop nodes will fail to load a VI containing a Python node with the message "The VI at the specified path is invalid. Select a valid VI for the VI interop node" Workaround: Create a VI and call the Python node inside of a subVI. If the node is not in the top-level VI, the Interop node will successfully load it.
