[news.eclipse.tools.gef] Re: How do I resize an element and the element

["Randy Hudson" <none@xxxxxxxxxx>]

It sounds like you might have two of the same policies installed. resize 
feedback is XOR, so if it paints twice, it will erase itself.

ResizableEditPolicy should be created inside the LayoutEditPolicy in 
createChildEditPolicy(...). You shouldn't install it from the editpart.
