how to auto-bind to a session after the entity becomes unman

outersky1 Mar 21, 2006 9:37 PM

I have an entity like this:

class Group{
//Lazy
List getUsers();
}

and it is used in web pages ( in the same JVM ).
but if the group object is passed from another page, it will become unmanaged,
so when invoking getUsers() method, exception will be thrown, because its lazy.

my question is , how could it be re-binded to a session?
so it can be used more naturally.

I use JBoss 4.0.4 RC1.

Maybe I can use a Proxy ?
if the lazy properties is accessed, the ProxyInstance makes it managed again. but how?
use EntityManager.merge()? it does not work.

managedObject = em.merge(detachedObject);
