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.

Reported Version: 2.0    Resolved Version: N/A    Added: 10/08/2012
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.

Return
Large number of strings in List Box or Drop Down control

Workaround: Tap on the item once to bring up the keyboard and then again to give it focus.

Reported Version: 2.2    Resolved Version: N/A    Added: 02/06/2014
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.

Reported Version: 2.2    Resolved Version: N/A    Added: 02/06/2014

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.

Reported Version: 2.0    Resolved Version: N/A    Added: 10/08/2012

Return
Changing data source polling rate causes load error when iPad is set to a different Language or Region Format

Shared Variables
355550

Return
No Edit button for recent server lists in connection dialogs

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
