[Zope] Having troubles using exUserFolder with Postgres

[David Mitchell]

Hello everyone,

I'm trying to set up exUserFolder to authenticate against a Postgres database.  
When I try to set it up, I keep getting this error:
    Error Type: NameError
    Error Value: global name 'MessageDialog' is not defined
immediately following the "Choose Authentication Type" screen.

Versions:
   Zope Version (Zope 2.6.0 (binary release, python 2.1, linux2-x86), python 
2.1.3, linux2)
   Python Version 2.1.3 (#1, Sep 19 2002, 13:15:46) [GCC egcs-2.91.66 
19990314/Linux (egcs-1.1.2 release)]
and I'm downloading the latest exUserFolder 0.10.10.  I've tried downloading 
it from both zope.org and sourceforge; the versions are identical, and both 
are failing for me in an identical manner...  I'm using Postgres 7.3.1.

My Postgres DB is accessible from Zope, and the DB connection is configured at 
the same level as I'm trying to install exUserFolder.  exUserFolder sees the 
DB connection fine.

I've tried lots of different combinations of configuration settings 
(Postgres/ZODB, with/without membership, etc.) and it's always failing for me 
at the same point.

I've tried manually building the "passwd" and "userproperties" tables as per 
the pgScheme.sql file, but that doesn't make any difference.

The Changes.txt file for exUserFolder describes what may be the same problem 
as being fixed in version 0.10.9.  Thinking the fix may have somehow 
disappeared from 0.10.10, I scrubbed 0.10.10 and installed 0.10.9 - problem 
didn't change.

Has anyone else come across this problem?  Any suggestions what else to check?  
For what it's worth, everything else Zope-ish (and otherwise) on this box is 
working fine - it's just exUserFolder that's giving me problems.

Thanks in advance for any help

Regards
