[ATL] Using external resources in ecore Meta-model [message #105850] Fri, 29 May 2009 19:58

Dear all,

I am new to ATL and currently trying several scenarios to get used to
the language. However, I have found a problem when using a Meta-model
that is build from several existing partial Meta-models.

The Meta-model has a containment relation (*) from one Eclass to a
Eclass defined in another Meta-model (in ecore imported as additional
resource). Somehow it does not seem to be possible to iterate over a
collection refering to the instances of the class defined in the
external Meta-model. There is no error message - the code within the
iterator is just not executed, though there are several items in the
collection.

Is there any sort of import mechanism or reference that has to be
applied in order to deal with the usage of Meta-models containing
external Meta-models? Does anybody know a good example showing the usage
of external resources within a ecore Meta-model?

Best regards,
Marius
