ScrollViewer is null

At runtime, when I pull up the window with my TreeViewEx control, I get an error in the InputEventRouter constructor that treeview.ScrollViewer is null. Shouldn't it be getting that from the Control Template?

I found my issue. We are overriding the Default ControlTemplate and including a ScrollViewer but not giving it the x:Name="scroller" attribute.
