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...

x:Name
