Sorry for rejecting first (used a "wrong" test-case), but after another test (which I set up properly as Chris describes) in current Zope 2.7 I get the same error. Seems to be a bug, which can drive you crazy when using ZCatalog.

This is not a bug, but wrong usage of ZCatalog. "sort_on" can only be used on registered metadata (see metadata-tab in ZCatalog), not on an index.

Okay, take a ZCatalog which has a FieldIndex called dateofpublication and some others.

Search it so that it returns some objects. Some of these objects have dateofpublication attributes, some dont, but all match the search criteria.

Now, add sort_on='dateofpublication' to your search terms.

I'd expect the objects without dateofpublication to be up the top of the results list.

What appears to happen is that they're dropped from the results completely, which really strikes me as a bug.
