[news.eclipse.modeling.gmf] Re: Problems with Duplicate action

["Mario Cervera" <mcervera@xxxxxxxxxxxxx>]

I can actually duplicate elements contained in the canvas so I've got 
something similar done in my editor, but my problem is that I can't 
duplicate elements contained in comparments (the item "Duplicate" doesn't 
even appear in the pop-up menu) and I don't see how that code can solve the 
problem :-(

Thanks

Mario
