I am getting a Unpickling Error. I am not sure it is a PTK-specific thing, as it seems to happen to PTK-Base dobjects, but nothing in the traceback seems to indicate PTKness. I am trying to import and export things from the same machine. Case number one: Portals. They don't seem to export without this error: --------------------------- <STRONG>Error Type: UnpicklingError</STRONG><BR> <STRONG>Error Value: invalid load key, '-'.</STRONG><BR> .... <!-- Traceback (innermost last): File /home/web/Vhosts/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /home/web/Vhosts/lib/python/ZPublisher/Publish.py, line 179, in publish File /home/web/Vhosts/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /home/web/Vhosts/lib/python/ZPublisher/Publish.py, line 165, in publish File /home/web/Vhosts/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /home/web/Vhosts/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_importObject) File /home/web/Vhosts/lib/python/OFS/ObjectManager.py, line 478, in manage_importObject (Object: ElementWithAttributes) File /home/web/Vhosts/lib/python/ZODB/ExportImport.py, line 284, in importFile UnpicklingError: (see above) --> ---------------------------- Case Number two: This also happens when I try to export a new test version of a PTK Aware version of the KnowledgeKit (freshly created), although it seems to be a '.' instead of a '-'. IMO, Portals, and objects that subclass Portal Classes need to be exportable _and_ importable.
