Hi, I was previously using the fastcgi solution but recently switched to use anser's solution as given in the how-to: http://www.zope.org/Members/anser/apache_zserver Everything has been working solidly (and fast!) until I found out that it can't seem to do a recatalog properly. Details are: Zope 2.1.4 + apache 1.3.9 on Debian potato. Zope is served off http://myserver.com/Zope/. I have a product called Sample that subclasses ZCatalog and reindexes its objects when edited. However, now when I tried to perform an edit, the following error message results: Error Type: ValueError Error Value: Uncatalog of absent id 'Zope/Sample/Object1' <!-- Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: CatalogAware) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_edit) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_edit) File /usr/lib/zope/lib/python/Products/Sample/Sample.py, line 184, in manage_edit (Object: CatalogAware) File /usr/lib/zope/lib/python/Products/ZCatalog/CatalogAwareness.py, line 190, in reindex_object (Object: CatalogAware) File /usr/lib/zope/lib/python/Products/ZCatalog/CatalogAwareness.py, line 186, in unindex_object (Object: CatalogAware) File /usr/lib/zope/lib/python/Products/ZCatalog/ZCatalog.py, line 357, in uncatalog_object (Object: ElementWithAttributes) File /usr/lib/zope/lib/python/Products/ZCatalog/Catalog.py, line 373, in uncatalogObject ValueError: (see above) --> My guess is that it was previously catalogued as 'Sample/Object1' but ZCatalog now gets the uid of the object as 'Zope/Sample/Object1'. Is there anything that I can do to overcome this? Will installing a SiteRoot in Catalog (my default catalog object) itself help? Any help is appreciated, Thanks Meng Kuan
