[Zope-dev] Unpickling Error: Invalid Load Key

[Bill Anderson]

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> 
....

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.
