Binding RadPropertyGrid.Item causes ViewModelLocator to fail?!

[Kristoffer]

If I put this in a MEFed dll (using MefedMVVM), I receive an exception:

<UserControl ...
     mefed:ViewModelLocator.NonSharedViewModel="MyViewModel">
<telerik:RadPropertyGrid Item="{Binding IsAsync=True}" AutoGeneratePropertyDefinitions="True" />

Error while resolving ViewModel. System.ComponentModel.Composition.ImportCardinalityMismatchException: No exports were found that match the constraint

I suppose this binding somehow conflicts with my MEF contract. Any ideas? Makes no sense... but if I remove the binding, it works!

Hi,

Unfortunately, we cannot give any guidelines, as we have never received similar reports. Would it be possible for you to send us a project that reproduces the issue, so that we would be able investigate it on our side?

All the best,
