hi, i'm trying to migrate a group of CMFCollectors from a Zope-2.6.2, Plone-1.0.5 site to a Zope-2.7, Plone-2.0 site. they're coming through mostly okay, but the Collector Catalog shows up on the destination site with 2 catalog entries for each issue, instead of just one. this wouldn't be so bad, except that NONE of the catalog entries are actually correct. one set of entries is mostly correct, except that they contain the wrong path to the collector issues (the location of the portal within the Zope site has changed). the other set of catalog entries has the correct paths, but are lacking all of the OTHER pertinent pieces of data, such as review_state, assigned_to, etc. what i'm trying to do is to copy the information from the old catalog entries to the ones with the correct path, so that i can run "catalog update" to purge the old entries. in an external method i've got some code like this: def fixCollectorCatalog(self): import string catalog = self.get_internal_catalog() oldbrain = catalog.search(query_request={'path':'/old/path', 'id':'42'})[0] newbrain = catalog.search(query_request={'path':'/new/path', 'id':'42'})[0] out = "%s: %s" % (newbrain.id, str(newbrain.assigned_to)) newbrain.assigned_to = ('testuser1', 'testuser2',) out += '\n\n%s: %s' % (newbrain.id, str(newbrain.assigned_to)) return out when i run this code, the output shows that the second access of 'newbrain.assigned_to' DOES actually contain the tuple that i hardcoded. this only lasts for the duration of the current request, though; the value returns to its original value on subsequent searches. how do i make my edits stick? or is there some other way to bring my catalog into sync with my collector's new location? many thanks for any help, -r
