    Just came across a null reference exception connected to TiltInteractionEffect:

    Message: NullReferenceException

    Stack Trace:

    at MS.Internal.XcpImports.Storyboard_Begin(Storyboard storyboard)
    at Telerik.Windows.Controls.TiltInteractionInfo.Clear(Boolean animate)
    at Telerik.Windows.Controls.TiltInteractionEffect.EndTilting(Boolean animate)
    at Telerik.Windows.Controls.TiltInteractionEffect.OnElementManipulationCompleted(Object sender, RoutedEventArgs e)
    at MS.Internal.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
    at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)


    Think it was during a page navigation/transition. Maybe you want to look into it ... if i find a way to reproduce it, I will let you know, currently it was the first time it happened.

    We will try to look into it and see what might cause it. It will also be great if you manage to find the way to reproduce the issue and share it with us - this will make things a lot easier to investigate and fix.

    I was able to recreate this with sample app (the source is at home and I'm uploading it along with a ticket this afternoon). I've got a thread in the RadDatePicker forums.

    I thought I'd narrowed the whole issue down to using the GestureListener from the WP7 Toolkit along with Teleriks controls. But now that you say it I'm am using navigation in the sample...

    Hello Matthew and Bernhard,

    We have been able to reproduce the issue that Matthew reported by using the project he attached. We will introduce a fix for this issue in the official Q3 2011 release. However, I suspect that the issue Bernhard came across is a bit different and it will be great if there is possibility to find out a way to deterministically reproduce the case so that we can debug it and see what goes wrong.

    Kind regards,
    Deyan
