Key: HHH-3843
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3843
Project: Hibernate Core
Issue Type: Bug
Components: envers
Affects Versions: 3.3.1
Environment: envers.jar 1.2.0, Hibernate 3.3.1, postgresql-8.3, jboss-4.2.3
Reporter: Michał Maryniak

There is a problem with unidirectional @ManyToMany relation.
This case is different than the one with inheritance:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-3830.
The example is trival and code is as simple as it can be.
A single Person can have many roles, and one Role can by assigned to many Person
entities.
@Entity
@Audited
public class Person implements Serializable {
(...)
@ManyToMany
public List<Role> getRoles() {
return roles;
}
(...)
}
and
@Entity
@Audited
public class Role implements Serializable {
(...)
}
And here comes a use case:
1) I create role 'admin'
2) I create role 'user'
3) I create person 'john' and add him a role 'admin'
4) I edit 'john' and add him second role 'user'
and I got an exception:
org.hibernate.NonUniqueObjectException with message: "a different object with the
same identifier value was already associated with the session:
[Person_Role_AUD#{roles_id=1, Person_id=5, REV=DefaultRevisionEntity(id = 7, revisionDate
= 2009-04-01 10:46:32)}]"
If I add one role and remove the second one, or if I only remove a role - an Exception
does not occur.
I attached a zip file with this simple SEAM project generated by seam-gen 2.1.1 GA.
I haven't included jar files, but project requires jar's "generated"
with seam-gen (2.1.1) and following jar's have been replaced with new ones:
2008-06-13 13:09 313˙898 dom4j.jar 1.6.1

If you wish - I can attach a file with my oryginal jar - but it would be a realy big file
;-)
