Hi,

I've created a ManyToMany relationship with extra columns and it works fine. But when I try to add Envers, the following error appears. I'm using Hibernate + Envers 3.6.10

{code:java}Initial SessionFactory creation failed: could not init listeners
org.hibernate.HibernateException: could not init listeners
     at org.hibernate.event.EventListeners.initializeListeners(EventListeners.java:205)

But When I use ibernate 4.1.0  the error is:

{code}
Initial SessionFactory creation failed: Unable to read the mapped by attribute for listAB in com.arplatia.ns.server.prueba.AB!

....{code}

Here are the classes with the annotations:

Class A

{code}@Entity
@Audited
public class A implements Serializable {
 
   //Sttributes
   //Construnctor methods
   //Getters and Setters
 
    @Id
    @GeneratedValue
    public Long getId() {
        return id;
    }

    @OneToMany (mappedBy = "id.a")
    @Cascade(CascadeType.ALL)
    @LazyCollection(LazyCollectionOption.TRUE)
    public Set<AB> getListAB() {
        return listAB;
    }
 
   //Hashcode and Equals
 
 
{code}

Class B

{code}@Entity
@Audited
public class B implements Serializable{
 
  //Attributes
  //Constructor methods
 // Getters and Setters
 
    @Id
    @GeneratedValue
    public Long getId() {
        return id;
    }
 
    @OneToMany (mappedBy = "id.b")
    @LazyCollection(LazyCollectionOption.TRUE)
    public Set<AB> getListAB() {
        return listAB;
    }
 
  //HashCode and Equals
 
}{code}

Class AB

{code}@Entity
@Audited
@AssociationOverrides({
    @AssociationOverride(name = "id.a", 
        joinColumns = @JoinColumn(name = "a_id")),
    @AssociationOverride(name = "id.b", 
        joinColumns = @JoinColumn(name = "b_id")) })
public class AB implements Serializable {
 
      //Attributes
     //Constructor Methods
     //Getters and Setters

    @EmbeddedId
    public ABId getId() {
        return id;
    }
 
    @Transient
    public A getA() {
        return getId().getA();
    }
 
    @Transient
    public B getB() {
        return getId().getB();
    }
 
     //HashCode and Equals
 
}{code}

Class ABId

{code}@Embeddable
public class ABId implements Serializable {
 
 
     //Attributes
     //Constructor Methods
     //Getters and Setters
 
    @ManyToOne
    public A getA() {
        return a;
 
    }
 
    @ManyToOne
    public B getB() {
        return b;
    }
 
   //HashCode and Equals
   }{code}

Can someone tell me what'is wrong with this code?
