[news.eclipse.modeling.gmt.amw] ATL2WTracer - problems

[lnaslavsky@xxxxxxxxxxx (Leila)]

Hi, 
I'm trying to run the first transformation of ATL2WTracer 
(Class2Relational.ecore to Class2RelationalWithTracer.ecore).
I'm getting the error in the console that starts with:


****** BEGIN Stack Trace

****** END Stack Trace


I looks like the transformation tries to set the wrong type to 'elements', 
so this error makes sense,  since elements is a list of 'ModelElement', 
which is sub-type of Element (not an 'OclModel').  


I'm currently using eclipse 3.1.1 (emf 2.1.1).
This transformation doesn't generate error when I use eclipse 3.1.0 (emf 
2.1.0), but then I can't use the AM3 plug-in, nor the AMW.

Do you have an idea of what I should be looking into (before I start 
changing the ATL2WTrace.atl code).

Thanks!
