The bug below doesn't describe why this was done.
156934: Disable use of unique attribute of eattribute to set unique
constraint
I didn't see any options that would turn this back on.
This is easy to remedy using annotations but I would like to know the reason
why so I can inform other people in my organization why they have to do
this.
Thanks,
-mike

The unique attribute only has a meaning for EMF if the feature is a many feature. In that case it is
used by Teneo to set unique on the onetomany. The unique attribute on onetomany is a teneo
extension. The unique attribute on the one-to-many is used to determine if a join table should be
used (yes if isunique=false) and if the hibernate mapping should have a list or set mapping.
The bugzilla has been updated with this information.
