Dropping a RadPane to DocumentHost cause Exception

[Carsten]

Hi !

I've a problem using RadDocking in Silverlight. If I try to move a RadPane which is added to a RadSplitContainer/RadPaneGroup to a DocumentHost/RadSplitContainer/RadPaneGroup the assembly throws an exception. The compass menu is highlighted to dock the RadPane after this exception but the whole application crashes!

This pane cannot be removed from parent, because it doesn't have one!   bei Telerik.Windows.Controls.RadPane.RemoveFromParent()
   bei Telerik.Windows.Controls.Docking.DocumentHost.AddPane(RadPane pane)
   bei Telerik.Windows.Controls.Docking.DocumentHost.AddSplitItem(ISplitItem itemToAdd)
   bei Telerik.Windows.Controls.RadDocking.OnDragCompleted(Object sender, DragInfoEventArgs e)
   bei Telerik.Windows.Controls.Docking.DragInfoEventArgs.InvokeEventHandler(Delegate genericHandler, Object genericTarget)
   bei Telerik.Windows.RadRoutedEventArgs.InvokeHandler(Delegate handler, Object target)
   bei Telerik.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RadRoutedEventArgs routedEventArgs)
   bei Telerik.Windows.RouteItem.InvokeHandler(RadRoutedEventArgs routedEventArgs)
   bei Telerik.Windows.EventRoute.InvokeHandlersImpl(Object source, RadRoutedEventArgs args, Boolean raisedAgain)
   bei Telerik.Windows.EventRoute.InvokeHandlers(Object source, RadRoutedEventArgs args)
   bei Telerik.Windows.RadRoutedEventHelper.RaiseEvent(DependencyObject element, RadRoutedEventArgs args)
   bei Telerik.Windows.DependencyObjectExtensions.RaiseEvent(DependencyObject element, RadRoutedEventArgs e)
   bei Telerik.Windows.Controls.Docking.ToolWindow.OnMouseLeftButtonUp(MouseButtonEventArgs e)
   bei System.Windows.Controls.Control.OnMouseLeftButtonUp(Control ctrl, EventArgs e)
   bei MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

Here is a part of the Shell.xaml:

<Grid x:Name="MainGrid" Margin="0" Grid.Row="1" Background="{x:Null}">
  <telerik:RadDocking>
    <telerik:RadDocking.DocumentHost>
      <telerik:RadSplitContainer>
        <telerik:RadPaneGroup x:Name="RadPaneGroupMainRegion" prism:RegionManager.RegionName="MainRegion" Background="{x:Null}" />
      </telerik:RadSplitContainer>
    </telerik:RadDocking.DocumentHost>
    <telerik:RadSplitContainer InitialPosition="DockedLeft" Width="380">
      <telerik:RadPaneGroup prism:RegionManager.RegionName="ExplorerRegion" />
    </telerik:RadSplitContainer>
    <telerik:RadSplitContainer InitialPosition="DockedLeft">
      <telerik:RadPaneGroup prism:RegionManager.RegionName="PropertiesRegion" />
    </telerik:RadSplitContainer>
  </telerik:RadDocking>
</Grid>

Any suggestions?
