[Setup] AttributeError : translation_service

[Nick Davis]

For comparison purposes, I have tried to run a 2.0.5->2.1.1 migration on 
both Zope 2.7.8 and Zope 2.8.4 .

On Zope 2.8.4 , the migration fails with AttributeError : 
translation_service.  This appears to be during the portal_catalog reindex.

If I go to a Zope 2.7.8 / Plone 2.0.5 instance, of course there is no 
problem clearing and reindexing the portal_catalog via the ZMI. If 
however I try this on a Zope 2.7.8 / Plone 2.1.1 with a Data.fs thats 
not yet been migrated, portal_catalog reindex fails with the same 
AttributeError : translation_service.

People might say "Why are you trying to do this? Let the migration run 
its course (on 2,7,8)". But my point is, if re-indexing the catalog 
doesn't work on an un-migrated site, surely it is doomed to fail AS PART 
OF THE MIGRATION on Zope 2.8.4?

It looks like Plone 2.1 expects there to be a translation_service 
sitting in the root of the Plone site. By creating a new Plone 2.0.5 
instance I proved this is not something that automatically get created 
on earlier versions of Plone.

Therefore, it looks like a chicken-and-egg situation, that re-indexing 
the catalog as part of migration on Zope 2.8.4, is expecting something 
to be there that won't be there until the site is already migrated.


Am I barking up the wrong tree here or is this a potential bug?
