>             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.
