reloading a detached object with a collection fails

Description

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]

Hi,

it's been almost 2 years and still not a simple response to this issue.
Why? Is it so hard to provide a simple answer where this issue will or wont be fixed?

Please reopen this issue or reply why it is closed.

I created a very small app to demonstrate the problem.
Though I cannot reproduce the "NonUniqueObjectException" another exception which should be related occurs.

The "aliases.conf" should be placed inside FireBird root folder.
The db schema is in "tables.sql".

toggle the boolean "USE_REFRESH" inside main() in order to verify that the reloading works if I use refresh().

Please let me know if there is anything else you need.

Sorry, I cannot understand the status change to "Resolved / Incomplete"
does this mean this issue is resolved in the latest 3.2BETA ?
