Martin et al,
in leiu of a fix for this should I be able to add annotations to change the attributes of these fields.
Is it possible to set the insert and update attributes of a mapped property through annotations ?
Thanks again

Hi Duncan,
It is partially a bug in the multi-inheritance handling. I solved this and will check this in later
today probably.
However on other issue remains: the uncodedmeasure and codedmeasure should have the same properties
in the hbm file. The difference happens because when I read the ecore files (to generate the hbm)
the uncodedmeasure has only one supertype (measure) while the codedmeasure has two supertypes:
measure and codable.
The strange thing is that when I open the ecores in the standard emf ecore editor that
uncodedmeasure has two supertypes (measure and codable).
When you look at your generated code and debug at runtime can you see which supertypes the
UncodedMeasure has?
Which version of emf are you using? I am using emf 2.3.

Is it possible to set the insert and update attributes of a mapped property through annotations ?
