[news.eclipse.modeling.mdt.uml2] Cast UML model elements

[Emilien Perico <emilien.perico@xxxxxxxxxxxxxx>]

Hi all,

I would like to replace elements in a model in an automatically way.
Actually I want to change to type of a model element by another, for 
example:
In an activity diagram, I want to replace all the callBehaviorActions by 
CallOperationActions.

I try to do it programmatically and I don't want to create a new object 
(and delete the old) but change the type (like a cast) to keep the same 
uuid.
I don't know if it is possible and I don't find a way.

Thanks,

Emilien Perico
