reloading a detached object with a collection fails
---------------------------------------------------

         Key: HHH-2119
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2119
     Project: Hibernate3
        Type: Bug

    Versions: 3.1.3    
 Environment: Hibernate 3.1.3
firebird 1.5.3.4870 with Jaybird-2.1.0
java 1.5.0_07
    Reporter: Gregory Kotsaftis


Hi,

1) I have a simple object <O> with a collection loaded and use <version> for both (no second level cache)
2) The object <O> is associated with session A, via <O> = load(CLASS, <ID>)
3) The session <A> is later closed because e.g. an exception occurs
4) Another session is opened later on, session B
5) If  load(<O>, <ID>)  is called an NonUniqueObjectException is thrown
    (a different object with the same identifier value was already associated with the session)
6) If instead I use the session.refresh(<O>) no exception is thrown, the object is reloaded ok.

It seems this issue might be related with: 
     http://opensource.atlassian.com/projects/hibernate/browse/HHH-511
but i cannot be sure.

Part of the stacktrace:

org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [gr.metadata.orthomed.db.Patient#23]
