[Zope] Putting objects into CoreSessionTracking?

[Chris McDonough]

It sounds like your session data objects are getting "ghosted" by the ZODB.
You may need your COM object class to subclass the Persistent class.

Objects that get stored in session data must play by the same rules as
anything else that gets stored in persistent storage.  For more information,
see http://www.amk.ca/zodb/guide/
(whoo hoo Andrew!)
