Hi Guys,
Just starting out with Udig. Trying to create a simple polygon on a temporary layer for users to edit within my own RCP, but seem to have a rendering problem. This is the error I see and my code. Is this the correct way to create an editor or should I extend from EditorPart and create an instance of the MapEditor (similar to the rcp tutorial MapView class)
Thanks in advance for any help
Andrew
