Isn't that very natural? "referencesf(data)" determines which objects are referenced by "data" and not which objects do reference the object the state of which is given by "data". Usually, the workflow history does not reference persistent objects. -- Dieter _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
