[Jboss-dev-forums] [Design of EJB 3.0] - Reassigned existing entities to other entities does not work

[LostInSpace2011 <nu...@jb...>]

I have the following scenario. A User has several Roles. The relationship between user and role is defined as a bi-directional many-to-many relationship.

- User A has Role A. 

- To retrieve Roles use :
User userA = ....
Roles roles = userA.getRoles()

- Then I contruct a new user and assign roles to it
User userB = new User();
userB.setRoles(userA.getRoles());

- Then I pass my use to the UserManagerBean to persist it
UserManager.createNewUser(userB);

-At this point what I percieve is happening is that all the roles which were previously associated with userA are now reassigned to userB. I have tried retrieving the "new" roles which resulted in : 

User userB = new User();
userB.setRoles(UserManager.getRoles());

- In this case the behaviour was correct :-)

The relationship between user and roles is a ManyToMany relationship without cascading and I am useing JBoss 4.0.3 RC 1 on JDK 1.5.0_04 on Windows XP.

Any suggestions on this. I believe this to be a bug.
