Hello All,
I am trying to extend VE to build GWT project. I have created a Label that creates a GWT label and the EditPart displays a draw2d.Label. When I create an instance of the label i get the following error

When I put a breakpoint in the code, I see that the AnnotationPolicy is looking for "GenericAnnotationLinkagePolicy" and is getting a "" class. why is this happening? Why am getting errors in the "cde" packages? I thought these are for "c" development.

Thank you
