The following items are known issues in Data Dashboard for LabVIEW 2.2 sorted by Category.
| ID | Known Issue | |||||
|---|---|---|---|---|---|---|
| Controls and Indicators | ||||||
| 370654 Return | Item Strings and Selected Item Index properties for a dropdown control cannot be bound using the mini palette to the output of a LabVIEW web service If you wish to bind the Selected Item Index or Item Strings properties of a dropdown control to the output of a LabVIEW web service method, you cannot do so using the custom palette that appears when you select the desired output terminal and tap "Create new indicator" Workaround: Place a dropdown control onto your canvas from the Controls palette, and link it directly to the desired output terminal of the Call or Poll Web Service item.
| |||||
| 372228 Return | Unable to bind more than 21 inputs or outputs of a LabVIEW web service If you connect a dashboard to a LabVIEW web service method with a large number of inputs or outputs, you cannot bind them all because the connection adorner will extend, and be inaccessible, past the bottom of the dashboard canvas. You can only bind 21 inputs/outputs in portrait mode, and 15 inputs/outputs in landscape mode. Workaround: If you require a LabVIEW web service with a large number of input or outputs, split the web service into multiple web methods.
| |||||
| 372873 Return | Changing certain properties of a control/indicator, and quickly deselecting the modified object may cause Data Dashboard to crash If you edit an object's property using a text editor in the property pane. Then, quickly dismiss the property page and deselect the object by double taping on the canvas, Data Dashboard will crash. Workaround: When editing an object's property using a text editor in the property pane, tap once to close the property pane and allow the property of the object to be updated before deselecting the object.
| |||||
| 432694 Return | Large number of strings in List Box or Drop Down control If a large number of strings exist in a List Box or Drop Down control, clicking the Property button may cause the control to lose focus once the keyboard is shown. Workaround: Tap on the item once to bring up the keyboard and then again to give it focus.
| |||||
| 443014 Return | Graph Axis limits do not show entire value when converted to scientific notation When using large values for the Maximum or Minimum settings on a Graph Axis, the number will be converted into scientific notation. The number originally entered is used by the graph but cannot be seen by the user once it is converted to scientific notation. Workaround: Manually track any axis settings that cover a small range of large numbers.
| |||||
| 449493 Return | Overlapping shapes and lines with opacity lead to drawing fragments When using shapes or lines with less that 100% opacity, visual fragments may occur when dragging the object over another shape or line. Workaround: Change opacity of any shapes or lines that show fragmentation
| |||||
| 443864 Return | Carriage Returns and Line Feeds do not appear in string indicators String indicators do not display Line Feeds and Carriage Returns properly. Depending on Operating System, they may show as spaces or not at all. Workaround: Avoid using Carriage Returns or Line Feeds in string data being read by Data Dashboard.
| |||||
| Operating System Specific | ||||||
| 370922 Return | Data Dashboard will not reflect changes to device regional settings until the app is removed from memory and relaunched If you are creating or running a dashboard, and you change the regional setting on your device, numbers and dates on the dashboard will not reflect the change in region until Data Dashboard is removed from memory and relaunched Workaround: Force quit and relaunch Data Dashboard
| |||||
| 371300 Return | Dashboards with images will not update to reflect new versions of the images synced from iTunes If you transfer an image to your iPad through iTunes, drop it on a dashboard, then update the same image on your computer and re-sync to your iPad, Data Dashboard will show only one version of the image since it is the same file. Workaround: Update the image filename when you edit it on your computer, before re-syncing with iTunes.
| |||||
| 434787 Return | Changing data source polling rate causes load error when iPad is set to a different Language or Region Format When an iPad is configured to use some languages and Region Formats other than English and the United States, Dashboards will give a load error after changing the polling rate on a Poll Web Service function. Workaround: Use English settings for the iPad or use the standard polling rates for web services
| |||||
| Shared Variables | ||||||
| 355550 Return | No Edit button for recent server lists in connection dialogs In the Shared Variable and LabVIEW Web Services connection dialogs, there is a list of recent servers you have accessed, with no Edit or Delete button to remove entries. Workaround: You can delete these entries by right-swiping on items in this list.
| |||||
| 443931 Return | Shared variables with an apostrophe in their name crash Data Dashboard Shared variables with an apostrophe in their name are selectable when binding a control or indicator, but they will show an Invalid URL error when run. This error appears because apostrophes are not supported by the shared variable protocol. Binding to these variables could cause a crash in previous versions of Data Dashboard but will now show an invalid URL error. Workaround: Remove any apostrophes from the shared variable name
| |||||
| Web Server/Web Services | ||||||
| 355550 Return | No Edit button for recent server lists in connection dialogs In the Shared Variable and LabVIEW Web Services connection dialogs, there is a list of recent servers you have accessed, with no Edit or Delete button to remove entries. Workaround: You can delete these entries by right-swiping on items in this list.
| |||||
| 358078 Return | Unable to bind a single dashboard to multiple web methods with the same name If you have two web methods in a LabVIEW web service with the same name, you cannot bind one through a Call Web Service item and the other through a Poll Web Service item. Workaround: Rename web methods to be unique.
