No, not all. However currently Cayenne checks that all attributes of
the join table are a part of the primary key. In your case it really
doesn't matter, and I think this check is dumb. For now to fix it, mark
artist_pk and exhibit_pk columns as PK in the modeler. I opened a bug
so this should be fixed in Cayenne soon.

There is an old task that is supposed to address this issue:
http://objectstyle.org/jira/secure/ViewIssue.jspa?key=CAY-38 . So it
won't be like that in the future.
