[ZPatterns] Weird Errors trying to move to Zope 2.4.0

[Chris Withers]

Hi,

I'm trying to get ZPatterns, LoginManager and Zope 2.4.0 to play nicely
together.

I'm using the version of ZPatterns Steve A released with TransactionAgents.
LoginManager is version 0.8.8b1
Zope is 2.4.0 Final.

I get the following error whenever I try to manage a folder that has a
LoginManager-based userfolder in it:

Traceback (innermost last):
  File Products/LoginManager/LoginManager.py, line 237, in validate
    (Object: ProviderContainer)
  File Products/LoginManager/LoginMethods.py, line 147, in findLogin
    (Object: PlugInBase)
  File Products/LoginManager/LoginManager.py, line 194, in getItem
    (Object: ProviderContainer)
  File Products/ZPatterns/Rack.py, line 56, in getItem
    (Object: ProviderContainer)
  File Products/ZPatterns/Rack.py, line 259, in _fromCache
    (Object: ProviderContainer)
AttributeError: _v_cache

Also, and I don't know if this is ZPatterns related, I get the following errors
for a whole range of products:

ConflictError: ('\x00\x00\x00\x00\x00\x00\x00\x00', '\x03>9\xad\xbf;\xcbD')

Any ideas on any of this would be very gratefully recieved...

cheers,

Chris
