I hate this exception more than any other exception in all of WO/
EOF. It's completely non-sensical relative to the root cause.
Entity Modeler yells a lot when you try to save a model like this, btw.

Is there something about posting to the list that makes things
suddenly seem clearer or what. I looked over my model again, and
discovered that EOModeler had not included column names for the IDs
in the join table. I thought it did this automatically when
choosing the Join in Many-to-Many function. Anyway, I added the
column names and reran the SQL, cleaned and rebuilt and now it
appears to work as it should.
Sorry for the wasted bandwidth,

I have a user class in my session class. I also have a club class.
I am trying to add a new club to my user and am using the
following code.
Session session = (Session)session();
EOEditingContext ec = session.defaultEditingContext();
Club club = new Club();
ec.insertObject(club);
club.setApproved(false);
club.setClubName(clubName);
club.setWebsite(clubWebsite);
session.user.addToClubs(club);
ec.saveChanges();
The code causes an exception at the addToClubs(club) line. I am
unsure as to why this is. I have used similar code before. My
guess is that it has something to do with the eomodel and the way
many to manys work versus one to manys. The other code I've
written like this before deals with one to many relationships. In
this case, the user-clubs is a many to many. From what I've read
in the docs, WO should be able to handle the linking table
automatically, but it doesn't seem to be working that way. Did I
miss something, or does this just not work this way?
Thanks,
Kevin
