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 System.Windows.Media.Animation.Storyboard.Begin()
at Telerik.Windows.Controls.Animation.AnimationManager.Play(FrameworkElement target, String animationName, Action completeCallback, Object[] args)
at Telerik.Windows.Controls.RadMenuItem.RunExpandAnimation(RadMenuItem menuItem)
at Telerik.Windows.Controls.RadMenuItem.<>c__DisplayClass5.<OnIsSubmenuOpenChanged>b__0(Object sender, EventArgs args)
at Telerik.Windows.Controls.PopupWrapper.OnPopupOpened(Object sender, EventArgs 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
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.
