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

["Mario Cervera" <mcervera@xxxxxxxxxxxxx>]

Hello,

I've noticed in my graphical editor that I can only duplicate elements that 
are contained in the canvas element but not in compartments. I'd like to be 
able to duplicate all elements. Does anyone know how to do this? I've seen 
that the Duplicate action is contributed in the plug-in 
"org.eclipse.gmf.runtime.diagram.ui.providers" so I can't modify those 
classes.

Thanks in advance.

Mario
