Sample odesign

NB : I'm using 1.0.0RC3 but it does not appear in the "version" list.

I have 2 container mappings : a list container (LC) and a freeform one (FC).
I'd like to define a drag and drop tool to allow one to drag an element from the list container and drop it onto the freeform container.

To do this I have specified my drop tool like this :
- drag source : diagram
- containers : FC (the drop target)
- mappings : the node mapping I want to drag

When I do this the D&D is not possible (no visual feedback neither).

I tried to add the dragged mapping as a reused node mapping in my freeform container (only as a test), the D&D is now possible but when it gets executed a ClassCastException occurs as described in ticket : https://bugs.eclipse.org/bugs/show_bug.cgi?id=428079


I provide an example odesign and an example project.
Steps to reproduce :
- import both projects
- open "test2" modeling project
- in My.ecore, open the diagram defined on the EPackage instance
- try to drag "a1" and drop it onto "pkg (mapping1)" => it is not possible
- try to drag "a1" and drop it onto "pkg (mapping2)" => the visual feedback is displayed but a ClassCastException occurs when executing the tool.
