After recently upgrading to Eclipse Helios, I get an error when creating a generator model from my ecore model (which always worked in the past). "A containment or bidirectional reference must be unique if its upper bound is different from 1." This worked in previous versions of Eclipse/EMF, and AFAICT it doesn't say which containment or bidirectional reference it is talking about. Is there any way to get more detail about what the problem is or other suggestions?

If you create the markers and double click it, you should navigate to
the object with the problem. You should end up on an EReference for
while upper bound > 1 and for which unique is false. You'll want to
change it to true.

Thanks! That did the trick
