Hi,

I'm trying to test our Silverlight application that contains the xamPivotGrid control with coded UI tests. Coded UI testing is a feature introduced in the Microsoft Visual Studio 2010 Feature Pack 2 that allows testers to record actions and then play them back in their web browsers.

For more information about Coded UI tests, please see http://msdn.microsoft.com/en-us/library/gg269472.aspx

When recording an action that starts loading data to the PivotGrid I get the following error:

Unhandled Error in Silverlight Application Object reference not set to an instance of an object.
   at Infragistics.Controls.Grids.AutomationPeers.PivotCellControlAutomationPeer. SelectedCells_SelectionChanged(Object sender, NotifyCollectionChangedEventArgs e)
   at System.Collections.Specialized.NotifyCollectionChangedEventHandler.Invoke(Object sender, NotifyCollectionChangedEventArgs e)

   at System.ComponentModel.BackgroundWorker.OnRunWorkerCompleted(RunWorkerCompletedEventArgs e)
   at System.ComponentModel.BackgroundWorker.<OnRun>b__1(Object state)

Stopping the action recording and trying to generate code for the test yields the following error:

System.NotSupportedException was unhandled
  Message = GetProperty of "SelectedItemsAsString" is not supported for the following control type: List. If this is a custom Silverlight control, verify that the property is supported for the control.
  Source = Microsoft.VisualStudio.TestTools.UITest.Extension.Silverlight

Do you have any ideas how to get around this and are there any plans on supporting coded UI tests in the future?
