Hello Folks,

I'm having a problem with versioning of a OneToMany relationship + JoinTable with envers.

Consider these classes:
(A Person can have many pets, but a pet belongs to just one Person.)

Person:

// imports omitted for brevity...

@Versioned
@Entity
public class Person {
 @Id
 @GeneratedValue(strategy=GenerationType.SEQUENCE)
 @Column(name="person_id")
 private long id;

 @OneToMany(cascade=CascadeType.ALL,fetch=FetchType.LAZY)
 @JoinTable(name="person_pet",
 joinColumns=@JoinColumn(name="person_id",referencedColumnName="person_id"),
 inverseJoinColumns=@JoinColumn(name="pet_id",referencedColumnName="pet_id"))
 private Set<Pet> pets;

 public Person(){
 this.pets = new HashSet<Pet>();
 }

 // gets and sets omitted for brevity...
}

Pet:

// imports omitted for brevity...

@Versioned
@Entity
public class Pet {
 @Id
 @GeneratedValue(strategy=GenerationType.SEQUENCE)
 @Column(name="pet_id")
 private long id;

 private String name;

 public Pet(){}

 // gets and sets omitted for brevity...
}

When I generate the database, envers creates a table called "person_pet_versions" which is supposed to contain the changes in the relationship between persons and pets.

The problem is that when I associate persons with pets, nothing is inserted into "person_pet_versions" table.

The test code:

// imports omitted for brevity...

public class Test {
 public static void main(String[] args) {
 EntityManagerFactory emf = Persistence.createEntityManagerFactory("testenvers");
 EntityManager em = emf.createEntityManager();
 EntityTransaction tx = em.getTransaction();
 try
 {
 tx.begin();

 Person me = new Person();
 me.getPets().add(new Pet("Fido"));
 me.getPets().add(new Pet("Max"));

 em.persist(me);

 tx.commit();
 }
 finally
 {
 if (tx.isActive())
 {
 tx.rollback();
 }

 em.close();
 }
 }
}

After executing the Test class, all the data is in the database, but the person_pet_versions table is empty.

I'm using:
Envers 1.1.0 beta2 for hibernate 3.3
Hibernate 3.3.1.GA

I already tested:
Envers 1.1.0 beta 2
Envers 1.1.0 beta 1
with
Hibernate 3.2.6

The docs say that a OneToMany + JoinTable versioning should work in envers 1.1.0 beta.

Am I doing something wrong?

Thanks in advance

by the way, this is an excelent framework. Its saving me a lot of time ;)
