Dear Dimitris,
I downloaded your files and put them in my project, however the demo.hutn
does not execute. I have Ganymede eclipse is that a problem? Epsilon was
successfully installed. One question is about the Families.emf file. Is it
needed? How is it generated? (I work with ecore files)
Anyway, the demo produces the error:
[Line: 8, Column: 4, Reason: Unrecognised classifier: XMI, Line: 9,
Column: 16, Reason: Unrecognised classifier: UnknownType, Line: 14,
Column: 13, Reason: Unrecognised classifier: UnknownType, Line: 17,
Column: 11, Reason: Unrecognised classifier: UnknownType]
Thanks a lot,
Nikos

Have you replaced your old Families.ecore with the new one or did you
put the new one elsewhere and registered it too? If you did the latter,
I'd suggest you delete the old .ecore and restart Eclipse to unregister it.

No.

..emf files are Ecore metamodels expressed in the the Emfatic textual
notation. You can find out more about Emfatic in
http://www.alphaworks.ibm.com/tech/emfatic and
http://wiki.eclipse.org/Emfatic.

This looks strange indeed. Does this happen with the .hutn file I
uploaded? BTW could you please send me your original .ecore and .hutn files?
