Hi,
I have several files to parse and then to check on a UML model, but i found out that the parsing order matters, in fact, when a method calls another one that is not yet parsed, an error occurs (OCL 1.2.3).
Does anybody know about a solution to this problem?
Thanks

Hi Skander

The OCL specification does not define whether forward references work;
indeed it doesn't actually define whether backward references work either.

MDT/OCL 1.x does not support forward references.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=187679 suggests
implementing forward references and raising a corresponding OMG
Issue to make the specification clear.

For now, you must avoid forward references.
