Need some help to get rid of an InvalidObjectReference exception In my zope product, when I try to put some specific object in the session, I get this :

A given persistent object can only be in one (ZODB-) database, not in several databases at the same time. You must copy the persistent object, when you want it to be stored (also) in another (ZODB-) database. You can use the "_getCopy(destination)" method to create such a copy. "_getCopy" is defined by "OFS.CopySupport.CopySource" inherited by most Zope objects. -- Dieter
