Hi
              everyone,
                   
              I hope I am in the good list for the following question.
              I’m currently working on MDT Papyrus which is a GMF
              generated editor.
            
                   
              For now we encounter some problem for regeneration one of
              our diagram.
        The
              problem is the following:
                   
              We are working on the Activity diagram. In this diagram
              for most of the elements we can have several containers:
        è    
                  The Activity Diagram
                container
        è    
                  And all the Grouping
                element (example : Structured Activity node)
        For now in the GenMap model the only
              container set is the Activity Diagram. If we add the other
              containers in the map, during generation a new element for
              each container will created. Or we want only one
              implementation of Structured Activity Node (for example)
              and not one for each element it can contain.
        For now the solution is manually add
              into the GenModel each reference into the “container” and
              “child” attribute. However each time we regenerate the
              genModel we lose all those references. So we have to add
              them manually again and it is quite pain full.
        So I’m writing here to know if:
        è    
                  There is any way to
                avoid when regenerating from GenMap to GenModel to
                override those manually added elements?
        è    
                  There is a way to
                reference existing element in container/child attribute
                to avoid creating new elements each time you add them.
         
        Thanks
              for any help you can give me.
