I tried doing a CustomScrollPanel with my own HorizontalScrollbar and VerticalScrollbar implementations which each return a Vaadin DrawingArea from asWidget(). The DrawingArea appears to be rendered but only underneath native scrollbars (which are not part of the DrawingArea Widget). I was expecting them to show instead of the native scrollbars. How do I ensure this is the case?
(P.S. I tried the example at GWT CustomScrollPanel example to no avail.)
