Bulk rejecting stale issues. If this is still a legitimate issue on ORM 4, feel free to comment and attach a test case. I'll address responses case-by-case. Thanks!

In an effort to clean up, in bulk, tickets that are most likely out of date, we're transitioning all ORM 3 tickets to an "Awaiting Test Case" state. Please see http://in.relation.to/Bloggers/HibernateORMJIRAPoliciesAndCleanUpTactics for more information.
If this is still a legitimate bug in ORM 4, please provide either a test case that reproduces it or enough detail (entities, mappings, snippets, etc.) to show that it still fails on 4. If nothing is received within 3 months or so, we'll be automatically closing them.
Thank you!

It seems like I only see this issue when I have TWO relationships refering to the same column, see the code bellow where I have two relationships refering to the column KODE_FS. If I add @Transient to one of these releationships I can't reproduse this issue.

I see this issue with both Hibernate 3.6.8.Final and 4.0.0.CR6. We are using Spring 3.1.0.RC1. We use native hibernate, not JPA.
When adding the following relationship to our Lesson domainobject I see this issue.
We see this issue when fetching a Lesson (which is the domainobject which has the resources attribute shown above) in the following testcase:
@Fabrice Daugan: Thanks for posting your comments! Since we see this issue in a "clean" fetching of an object I don't think we have any non persisted entities.

I've reproduced this issue many and many times.
But each time this was due to a non persisted entity refferenced as primary key (and maybe composite).
To avoid this, the rule is simple, even with cascade persist, allways persist the keys before the main entity :
em.persist(entity1);
em.persist(entity2);
em.persist(new Entity(entity1,entity2);
The following error does not occur every time, but in 75% of all program starts.
The error either occurs on one of the first queries to the database, or does not occur at all.
We solve this issue by simply restarting the application and trying again. It also happens with other applications, not only this one.
