    Auditing behavior of Joined Table Using @ManyToMany

    bucpatr

      I have two audited entities joined by a ManyToMany relationship.When I look at the database after a persist I can see that there is a auditing table for each entity and an auditing table for the join table as expected. What I'm not clear on is the expected behavior when a change is made to the owning entity that does not involve the mapped entity. Currently, it is adding a revision to the auditing table for the join table every time even if the update has nothing to do with the mapped entity. Is this a bug or is it supposed to do that?

       

      My code looks something like this:

       

      //the owning entity
      @Entity(name = "Brand")
      @Table(name = "brands")
      @Audited
      public class Brand
      {
      
          @Id
          @DocumentId
          @GeneratedValue(strategy = GenerationType.AUTO)
          protected Long id;
      
          @ManyToMany(fetch = FetchType.LAZY)
          @JoinTable(name = "brands_to_managers", inverseJoinColumns = { @JoinColumn(name = "person_id", referencedColumnName = "id") }, joinColumns = { @JoinColumn(name = "brand_id", referencedColumnName = "id") })
          @AuditJoinTable(inverseJoinColumns = { @JoinColumn(name = "person_id", referencedColumnName = "id") })
          public Set<Person> brandManagers;
      
          @Column
          public String name;
      
      }
      
      //the owned entity
      @Entity(name = "Person")
      @Table(name = "persons")
      @Audited
      @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
      public class Person
      {
      
          @Id
          @DocumentId
          @GeneratedValue(strategy = GenerationType.AUTO)
          protected Long id;
      
           @Column(nullable = true)
           public String username;
      
      }
      

       

       

      Using the code above, if I were to make a change to Brand.name and persist it to the DB, in the brands_to_brand_managers_AUD table I would get a new revision with a REVTYPE of 0. I've also noticed that removing one of the owned entities from the realtionship does not result in a delete revision being added to the brands_to_brand_managers_AUD table. any help on this would be much appreciated.
