A different object with the same identifier value is already associated with the session 2

This problem, I assign the object to null, it is also very useful. In my system, the update is good, but the insertion is not useful. Before the change, is inserted easy to use, and the update is not used. It was a problem in the system, but the catch just caught, from but, did not print out the log, Finding the reason is hard to find. When you are in a high database, it is best to print out the information in the exception capture.
