[news.eclipse.modeling.gmf] Re: Problems with the Mapping model

[tigerkatten@xxxxxxxxx (Linda & Anna)]

Maybe we are giving some redundant information now, but we would like to 
explain again what our class diagram looks like.
We are making an editor for UML Statemachines and our ecore diagram looks 
like this:

We have read through the whole thread and realized that that there was 
some things that we continued to ask that you had already explained. But, 
there is still some things that we donŽt understand (surprise :-) )

We guess that you mean create only one link mapping. For example we can 
create one like this:
<Transition{Transition.sources:State->Transition.targets:State}/Transition>

But then how do we get ONE link mapping to connect to the three kinds of 
nodes. If it is somewhere in the gmfmap, please specify where.

We have never written any ocl and donŽt really understand how to write the 
constraints in it.  We have looked at your example but we still donŽt 
understand how we should do it. (We added link constraints in the mapping 
model to the link Mapping and wrote some code snippets in the body part 
that didnŽt work.)Is there a way to set this in Java instead :-)

This is the first time we use GMF or any kind of framework in Eclipse by 
the way and we understand that we ask a lot of stupid questions. Sorry 
about that....
