I have followed your recommendation for qualifying names and it worked,
although the gmfmap validation was showing errors. Luckily I discovered
another post of another guy that you adviced him to ignore the validation
errors and run an instance of the editor.
I did that and altough the validation errors on .gmfmap exist the
constraint runs ok. Although it always gives me a constraint validation
even if the two values are equal.
Let's say that I have two instances: one of the Metamodel A---Model
A---Value A and one of the Metamodel B---Model B---ValueB.
What I don't understand is how does it know, when I am running the
validation on the editor of Model A, that it should check also Model B. My
guess is that it does not know and therefore it cannot check the Value A
of Model A against the Value B of Model B. That's why it the constraint
check fails each time.
Do you agree on this? Is there a way to resolve this so I can get it
working?
