Are you using any virtual hosting setup of any kind? If so, switching from using a base class of CatalogAware.CatalogAware to CatalogPathAware.CatalogAware might solve this problem...

Then I started to index instances of a regular ZClass as well. Then I added another index, to catalog an additional property of this ZClass, and hit "Update Catalog". When Zope returned from updating, there were no records in the Catalog, though the Vocabulary was intact. I see that I cannot search for the DataSkin metatypes using the "Find Objects" ZCatalog tab: they don't show up in the "Find objects of type" field. So perhaps this is why updating failed. However, now the Catalog is not accepting any entries. I originally did the cataloging using this kind of loop on all the classes I wanted indexed:: ids = container.Roundup.Issues.defaultRack.getPersistentItemIDs() for id in ids: object = container.Roundup.Issues.defaultRack.getItem(id) Catalog.catalog_object( object , string.join( object.getPhysicalPath() , '/')) When I try to run that again, I still get "There are no objects in the Catalog." upon return. When I run it using a newly created catalog ('testCatalog') instead, it works fine. Could anyone perhaps explain what's happening here?
