I was just discussing this on the Cayenne list last week. I chose to get the hash code of the object (customer) and return it to the keyExpression. I figured that was probably unique enough for my uses (unlikely to have clashes over a small set of objects). Also, this would work for new/uncommitted objects (no primary key) as well as persisted ones. Seems to work OK in my preliminary tests.

I have an additional question, if you don't mind: keyExpression="id" I presume that the "id" in keyExpression is the (customer)id in the (Customer)object. Will this work when i render new / empty objects?
