This seems like a likely culprit, although on the surface I thought I was wrapping 'B'. Based on another comment I tried reimplementing the system so that instances of 'C' also had a ZMI representation, and I started running through the system looking at the repr() of these instances (both 'B' and 'C'). What I saw was that 'B' would say: <B instance at 2a9e9274e0> (or some other mem address) while 'C' would say: <C instance at /gg/some/path> My knowledge of these things is poor but that would imply that B is not properly wrapped? FWIW when I instantiate 'B' I do a _setObject() and then a _getOb() and use the return value from that, my understanding being that this is what wraps the object. > Does your logfile contains unexplained entries?

The error that gets thrown doesn't appear to be a normal Zope error (e.g. AttributeError, ProgrammingError, etc), it just says (in italics) something along the lines of 'Psycopg_database_controller cannot be found' w/o traceback info, etc. Thanks -J _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
