Name and version of the database you are using:
MySql 5.0.15nt
The problem arises when I enable debugging. (log4j.logger.org.hibernate=debug) When disabled, it works fine.
It appears that when printing out debugging information, the id of the owning object (Tournament) is printed instead of the value of the property-ref. Since these are of different types (String vs Long) there is a class cast exception.
Can someone verify this is truly a bug or I have misconstrued how to do property ref associations?
Thanks

P.S. if verified a bug, I will submit to JIRA
