Hello,

I'm facing a problem when I use a many-to-one relation.
I've looked at the reference manual (the Cat example) and searched the forum but I don't seem to find a post with the same error/behaviour as I have. So I was hoping you guys could help me out.

The problem occurs when I add a many-to-one relation to my mapping file (see below). If I try to query or load objects which I have not created in the currently active session then the many-to-one component causes an exception to be thrown (see stack trace below). If I query objects which I created in the same session all is going well. However I would like to be able to load some existing data from the database.

I created a minimum JUnit test which can (hopefully) reproduce the problem. If you run the test as it is posted you don't have any problems because the objects are created in the session in the SetUp method and are removed from it in the teardown method. So you can easily run the test multiple times without having an exception.
To reproduce my problem you have to:
- Comment out the delete section of the teardown function and run the test once more. No problem at the this stage. (The objects are succesfully inserted into the DB and not deleted).
- Comment out the create section in the setup function (if we don't do this we will off course have duplicate key exceptions). Now you should see the Error stack mentioned below.

I really hope you can help me with this.

Thanks in advance,
Kind Regards,

Niels Soeffers
