The attached files reproduce the problem. As you will see in the source files there are different variations: if you turn off the cascade on the association, it will work.
The exception is:
Exception in thread "main" org.hibernate.PropertyValueException: not-null property references a null or transient value: Computer._computersBackref
Linux Sun JDK 1.6
Just tried it on latest 3.5, it's still there. Also the zip is not really well named, it's indeed a set and not a list.
Does this duplicate HHH-1654?
In an effort to clean up, in bulk, tickets that are most likely out of date, we're transitioning all ORM 3 tickets to an "Awaiting Test Case" state.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.
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!
