    Hello Telerik!

    In my application I dynamically add and remove RadMenuItems to a parent RadMenuItem, but occasionally I get the following Exception when submenu is about to display:

    Unhandled Error in Silverlight Application
    Code: 4004
    Category: ManagedRuntimeError
    Message: System.InvalidOperationException: Animation target not specified.
        at MS.Internal.XcpImports.MethodEx(IntPtr ptr, String name, CValue[] cvData)
        at MS.Internal.XcpImports.MethodEx(DependencyObject obj, String name)

        at Telerik.Windows.Controls.Animation.AnimationManager.Play(FrameworkElement target, String animationName, Action completeCallback, Object[] args)

        at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String

    I seems to appear when I remove an item, sets IsEnabled to false on the parent, adds a new child and sets IsEnabled to true again on the parent menu. The Exception makes my application to crash and I seem unable to catch it (that is I can catch it in the App-class, but not before that).

    I'm using 2010_3_1129_DEV_hotfix binaries.

    The problem went away when I upgraded to the latest binaries.
