Hi all.

I am trying to create a diagram and it is working fine so far.
But, now, I would like to put in some constraints about the number of
specific nodes present in the canvas (like "only one start node in a
diagram").

Could someone help me there?

Thanks.

Geo

I must also say that I cannot change the model. It must be done in the
mapping. And I cannot find anything that would "count" in the model so I
am stuck.

Please help

Check .size() operation for the collections in OCL specification.

I am very confused with the GMF constraints and cannot find something
(doc, tutorial,etc...) to help me out.
I tried something like this. But without success. I can't find out where
to find the collection or how I can create one.

Could you point me to something?

Thanks.
