    The first time I click on the expander for a load on demand item, the little circle appears, but never goes away.  The LoadOnDemand event doesn't appear to fire as well.  When I click on a second on demand item I receive the following exception...


     'LoadingVisualAngleTransform' name cannot be found in the name scope of 'System.Windows.Controls.ControlTemplate'.



    Here is the xaml...

    <telerik:RadTreeView x:Name="ExtendedTreeView"
         ItemsSource="{Binding TreeViewItems}"
         BorderThickness="0"
         IsEditable="True"
         IsLoadOnDemandEnabled="True"
         LoadOnDemand="ExtendedTreeView_LoadOnDemand"
         telerikAnimation:AnimationManager.IsAnimationEnabled="False"
         FocusVisualStyle="{x:Null}">

    The loading transform wasn't named in my template.  Adding the 'LoadingVisualAngleTransform' name solved the problem.

    Thanks,
