Hi,

The scenario:

I'm working with some pojo Article.

1) createSession()
2) session.merge(Article )
3) session.saveOrUpdate(Article)
3) closeSession()
// Article dbVersion=2
....
4) createSession()
5) session.merge(Article )
Here I'm getting StaleObjectStateException with strange state values. When I inspect in debugger variables of DefaultMergeEventListener.entityIsDetached() I see that entity.dbVersion=2, while target.dbVersion=1.
So, the target variable contains very old version of the Article. How can I prevent loading of old version? (where does it come from?)

The application is multi-threaded in its nature, however the process of handling of Article instance is serial, so I don't see place for multi-threaded collisions. Of course, each thread is using different instance of Session.
