That works. given A and B, two objects whose classes inherit from persistent.Persistent, A.foo = B and B.bar = A will work as you expect. Haven't seen clear requirements for this from you, but maybe I missed them. Gary ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
