Fabio Maulo closed NH-1965.
---------------------------
Resolution: Obsolete
The test is available in our sources; it does not fail in NH3.2
> CLONE -Lock(obj, LockMode.None) not working when there is collection

> Key: NH-1965
> URL: http://216.121.112.228/browse/NH-1965
> Project: NHibernate
> Issue Type: Improvement
> Components: Core
> Affects Versions: 2.1.0.GA
> Reporter: Offir
> Priority: Major
>
> As we all know, there are two means of re-attach a detached object: 1) sess.Update(obj) and 2) sess.Lock(c, LockMode.None);
> In 1.2.0 Alpha1, the second meanning does not work. If there is a collection in the entity, Lock() will throw an exception (but now error was found in the log file).
> Here are the code and the mapping file, which can also be found in the attachment.
> ////////ReAttachTest.cs////////////
> [TestFixture]
> public class ReAttachTest {
> [Test]
> public void ReAttachCatTest() {
> Configuration cfg = new Configuration();
> cfg.AddAssembly("NHSessTest");
> ISessionFactory fct = cfg.BuildSessionFactory();
> ISession sess = fct.OpenSession();
> Cat c = new Cat();
> sess.Save(c);
> sess.Clear();
>
> sess.Update(c); //Update() works fine
>
> sess.Clear();
>
> sess.Lock(c, LockMode.None); //Exception throw here
>
> sess.Close();
> }
> }
