Hibernate version: 3.1.3

Before I call .merge (Object) on the session I had all the ID columns populated. But the .merge () method returns the object without any key column values. This happens for the parent and all child objects in the colletion.


Is there a way to aviod this issue? Any workarounds. I don't need to update the object after merge.




THANKS

Hello Friend:

If u see the hibernate´s API document about the method merge(Object) of the class Session, it indicate:

[u]Copy the state of the given object onto the persistent object with the same identifier. If there is no persistent instance currently associated with the session, it will be loaded. Return the persistent instance. If the given instance is unsaved, save a copy of and return it as a newly persistent instance. The given instance does not become associated with the session. This operation cascades to associated instances if the association is mapped with cascade="merge".[/u]

I hope this can help u to solve ur problem.

In my case the object was a pre persisted one. I just want to update it in a new session. Why would it remove the ID column data ....?

THANKS!
