Hi all! When the object is in persistent state and i change its properties when the transaction is commited the properties are synchronized automaticaly. But this is a problem in some situation is there a way to disable this automatic synchronization so the object is updated only when i invoke update() method.

You can
1. rollback the session instead of commiting, if you don't want to change the data
2. change the data tentatively elsewhere (e.g. a clone of your entity)
3. set the session's flush to NEVER until you're sure you want the changes[/list]
