Hi,

Is what I'm doing correct? basically, I start a transaction, obtain a list of objects, close the session then:

1) I can loop true the list, I assume these are detached objects, they are still accessible
2) I open a new Session and Transaction, then set some properties on the objects in the list obtained from old instance of Session, and use new Session to update, it still works, Am I doing correctly?

Thanks,

Angelo

Transaction tx;
Session session;

session = sessionSource.create();
tx = session.beginTransaction();

Query q = session.createQuery("from Transit");
List lst = q.list();
tx.commit();
session.close();

// accessing detached objects

for (Object o : lst) {
Transit tf = (Transit) o;
}

session = sessionSource.create();
tx = session.beginTransaction();

for (Object o : lst) {
Transit tf = (Transit) o;
tf.setCount(100);
session.update(tf); // why I can update a detached object
}
tx.commit();
session.close();

Ofcourse that is fine. This happens in almost all real-worls apps. Usually in one session you loads the object and pass it on to the view layer. The view layer makes some modifications and submits the modified object to the DAO layer. DAO layer now will have to open a new session and a transcation for updating the changes.
