EntityUpdateAction does not do a deepCopy for loadedState, making change detection of Custom Type based on a Collection not working
-----------------------------------------------------------------------------------------------------------------------------------

         Key: HHH-2314
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2314
     Project: Hibernate3
        Type: Bug

  Components: core  
    Versions: 3.2.0.ga, 3.2.1    
 Environment: Hibernate 3.2.1.ga, SQLServer and Oracle 10
    Reporter: arnaud.roger at gmail.com


We have a User object with a roles HashSet<String> that is map with a CustomType to VARCHAR in the database using a comma separated format.

When this Entity is manipulated through a long transaction hibernate does not detect that the Entity is dirty and does not flush the change to the database.
This does not happen in Hibernate 3.1.1

After tracing through Hibernate I identified the bug. This is due to a change in the 3.2 branch in EntityUpdateAction

http://fisheye.jboss.org/browse/~br=tag%3Av321/Hibernate/tags/v321/Hibernate3/src/org/hibernate/action/EntityUpdateAction.java?r1=10125&r2=10614

The deepCopy is done only when hasUpdateGeneratedProperties() is true, which I is not for our User object. So the set is not deepCopy and the lastUpdated array got a reference to the the same set as the user object. 
Any modification is so done in the lastUpdated and the User entity, making the object non dirty.

rollbacking to the 3.1.1 version of this file probably fix the issue.

Regards
Arnaud

PS: I'd try to produce a simple test case in the next days
