OK, I thought I'd give the new alpha a try with an old site, to check the upgrade procedure. I have a problem. If I go to create a ZClass, which inherits from ZCatalogAware, or I click on the update catalog link in a Catalog, I get the following traceback: Traceback (innermost last): File /home/web/Alpha/lib/python/ZPublisher/Publish.py, line 224, in publish_module File /home/web/Alpha/lib/python/ZPublisher/Publish.py, line 189, in publish File /home/web/Alpha/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File /home/web/Alpha/lib/python/ZPublisher/Publish.py, line 175, in publish File /home/web/Alpha/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_catalogReindex) File /home/web/Alpha/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_catalogReindex) File /home/web/Alpha/lib/python/Products/ZCatalog/ZCatalog.py, line 282, in manage_catalogReindex (Object: ElementWithAttributes) File /home/web/Alpha/lib/python/Products/ZCatalog/ZCatalog.py, line 369, in catalog_object (Object: ElementWithAttributes) File /home/web/Alpha/lib/python/Products/ZCatalog/Catalog.py, line 373, in catalogObject File /home/web/Alpha/lib/python/SearchIndex/UnTextIndex.py, line 251, in index_object File /home/web/Alpha/lib/python/SearchIndex/Lexicon.py, line 165, in Splitter AttributeError: (see above) Since I couldn't do anything as 'superuser', I created a manager user, and am logged in as that user. Could the new ownership stuff be causing this? Bill
