Hi Leila,

First, about the warning:

Did you create one specific metamodel extension? For instance, you should not use the 
"base extension" and the "traceability extension" together, because they both have 
ElementRef elements. You can check on the .ecore file with the weaving metamodel to see if 
it has more than one ElementRef.

Second, I didn't manage to reproduce the "internal errors". These errors typically happen 
when the transformation cannot find (or configure) the input models. Do you use the AMW 
model handler?

The method setElementIDbyRefType does not have any return type (I just corrected the 
description on the Wiki), so  this could be the cause of the internal error (if you were 
trying to get its result).

Let me know if this information helps you.

Regards,

Marcos.
