Load and save an object in the same session and transaction

Dear all,
I load an object, I modify it and I want to update it. But when I update it I have the following message error :

Code:

Another object was associated with this id (the object with the given id was already loaded): [fr.gouv.finances.dgi.opale.commun.transverse.persistent.AdherentPersistent#20030100001243]

Any idea ?

A loaded object instance need not to be reattached to the session (session.update())

Looks like you do

Code:

myClass1 = (MyClass) session.load(MyClass, id)
myClass2.setId(id); //same id than myClass1
session.update(myClass2);

You must update myClass1 or evict it from the session

And how can I evict it from session, close the session ?

session.evict()

Try saveOrUpdateCopy, should be better in your case

If I use session.evict(myObject) I have the same error ans saveOrUpdateCopy doesn't exist in my release !

You must evict the object which is actually attached with the session. ie the session.load(MyClass, id) object. The other one isn't attached to the session, and that's the problem
