Given this definition:
<ig:XamComboEditor x:Name="productCombo" ItemsSource="{Binding Products}" SelectedItem="{Binding Product, Mode=TwoWay, ValidatesOnExceptions=True, NotifyOnValidationError=True, ValidatesOnDataErrors=True, ValidatesOnNotifyDataErrors=True}" DisplayMemberPath="ComboDisplayName" HorizontalAlignment="Stretch" Margin="0" VerticalAlignment="Center" AutoComplete="True" CustomValueEnteredAction="Add" DataObjectRequested="productCombo_DataObjectRequested"/>
I get this exception trying to add an item not currently in 'Products' ie as a consequence of the CustomValueEnteredAction.

Hi James,
I apologize this post has not yet been answered by anyone. I was wondering if you found the solution to this issue? If this was never resolved and if you are willing to revisit it, would you be willing to extract your code and XAML into a small Silverlight sample that reproduces the problem? With that sample I can identify what can be done to remove the exception and if you've come across a bug.
Sincerely,
No, it's still a problem. (Although I'm using 10.2, I've not yet upgraded the app)
The attached solution demonstrates the problem. Click in the 'Reference' field & drop down the combo - type a new entry and tab off. I get a JIT debugger window:

Hi,
Would you be willing to send me the version of the Infragistics DLLs you are using. You can locate the DLLs in the Program Files folder and get the Version by looking at the DLL Properties.
I am not able to reproduce this exception with the versions of 10.2 that I have.
Thank you,
The Infragistics dlls ( InfragisticsSL4.Controls.Editors.xamcomboeditor.v10.2.dll, InfragisticsSL4.Controls.Grids.XamGrid.v10.2.dll and InfragisticsSL4.v10.2.dll) are 10.2.20102.1029
James
It appears to be fixed in 10.3 as I cannot reproduce the issue. Please let me know if you have any problem.
Thanks!
Given the choice, I'll probably go straight to 10.3. I assume that it's fixed there too?
There is a service release for version 2010.2. Would you be willing to download and upgrade your version of the DLLs and let me know if the problem persists?
Thank you!
