Guillaume,
The UML project has an extended GenModel and has specialized some of the
templates for generating the code. Perhaps that's part of what's going
on...
I do have UML installed, so if you export to a zip the project with your
model, I should be able to reproduce what you're seeing and determine if
there's a bug in how EOperations are handled in a multiple inheritance
scenario...
I suspect that you need to use UML's extended GenModel if you extend the
UML model. I've added the UML2 newsgroup to the "to"list of the reply
for their comments about how one should extend UML2...
