Hi Alex--

Thanks for the good info. I've looked into your suggestion and am having 
a hard time getting some of the pieces together. My EditPart class's 
constructor takes in a View object, but I'm having a hard time turning 
it into a Viewer class. Also, I've found that the 
getVisualPartRegistry() you mentioned is probably getVisualPartMap(). It 
is in org.eclipse.gef.ui.parts.AbstractEditPartView class.

Somehow, I need to take the View class that I start with and get 
reference to AbstractEditPartViewer (or another viewer class that can 
return the VisualPartMap). Can you provide some guidance on this? Also, 
should I even be doing this in the constructor of the EditPart or is 
there another place better suited?

Thanks for your help.
