Duplicate key question

I'm using Ramon Leon's MagritteGlorp package, which ties together the extremely useful Magritte and Glorp packages, but must not be using it quite correctly. When registering an object that has a reference to an already stored object, it seems to attempt re-insert the referenced object. For example: objA := ADescriptorSystem getSession execute: (A find where [:ea | ea name = 'hello']). objB := B new. objB a: objA. session := B getSession. session beginUnitOfWork. objB register: objB. session commitUnitOfWork. raises a 'GlorpDatabaseWriteError: ERROR: duplicate key violates unique constraint' error. I thought it might be because I am using one session to load the object and another session to register, but believe I've also tried doing everything in one session. If it is of any help, the reference description is of type MAToOneRelationDescription. On another project, I tried MAMultipleOptionDescription with the same error. Any ideas on how to make it recognize the object is already stored and hasn't changed? Thanks, Brian.
