In both 2.2.0b3 and a CVS checkout from 7/1, there's a small bug in ZCatalog.manage_addZCatalog. If you call it and don't supply a vocab_id argument, vocab_id defaults to None. But the code turns that into the *string* "None", and when ZCatalog's init method sees that it thinks its a real vocabulary name and does not create a default vocabulary. I fixed it by changing: vocab_id=str(vocab_id) if vocab_id == 'create_default_catalog_': vocab_id = None to if vocab_id is not None: vocab_id=str(vocab_id) if vocab_id == 'create_default_catalog_': vocab_id = None although a better fix might be to make the default value of vocab_id be the string "create_default_catalog_". I've put this in the collector. By the way, the collector pages ought to have a link explaining what format patches should be submitted in. I just stuck the above in my descrpition text, since I couldn't find docs on the patch format. --RDM
