Your second problem (trying to add references to non-persistent objects to a persistent object) is a hard one. If you post what you're trying to do specifically, maybe someone can suggest an alternate design pattern. By default, Cayenne attempts to initialize persistence if it finds a non-persisted object being added to the object graph. Maybe the solution is to construct your non-persisted objects in a "COMMITTED" state so that Cayenne doesn't have issues with them.

And what about the NullPointerException I mentioned in the first email?
