Reattaching a detached instance: hibernate lock()

it fixes the issue I'm a bit confused. I don't understand why the changes made before lock()/buildLockRequest() are propagated to the database.
//Changes made before the call to lock() aren’t propagated to the database
item.setInitialPrice(new BigDecimal(179));
sessionTwo.buildLockRequest(LockOptions.NONE).lock(item);

NHibernate NonUniqueObjectException when reattaching objects to the session (with Lock)

it fixes the issue Can you use a fresh session (or transaction) for processing each item and for updating the UserSetting? This would probably prevent the NonUniqueException.
Cheers,

Reattaching and manipulating a detached instance in Hibernate (JPA)

around this issue I think you can just use the detached Object o and after just to use the session.update(o).
Try to watch this video tutorial, maybe it will be useful!

Make Hibernate treat detached objects as same instance

this will help What I did is, instead of a map, use separate collections for the parent and child objects. After that I just persisted the parent object collection and that was It (because child object can't exist without a parent object, but parent can without child objects, otherwise I could also instead persist the child objects).
So the problem with map was, that although you add a value to a specific keys collection values from another keys collection values, It does not reference the same object, i.e. It creates a new one for the other key collection, which is why in this case you get duplicates when persisting the key values (which are the parent objects).
