Hi all,

I did not find a better way to discuss this article. Maybe there is one existing. The artcle says:

Quote:

Java is usually the option when the expression logic represents excessive complexity or requires direct access to Ecore reflective API

In my opinion this is not 100% right. I can access the Ecore API by using this cast:

self.oclAsType(ecore::EObject)

I think this option should be documented somewher. What do others think?

Ralph,

I think the OCL folks have documented how to use it for constraints;
something that wasn't so easy before the EMF 2.6 release...

Given the documentation is in the wiki, you should feel free to
contribute to it.
