[news.eclipse.modeling.gmf] Object multiplicity in the diagram

[marcin_cylke@xxxxx (Marcin Cylke)]

Hello
I'm generating a GMF editor from an ecore model. I have some parent object 
that should be placed on the diagram - lets call it A. It can have one 
object B and 0..* objects B. I've specified that condition in Ecore model, 
but generated diagram does not obey that, and I have to place object B by 
myself. Moreover, I'm able to place more B-objects than one.

How can I force such object's multiplicity?
