EntityListeners @Transactional of Demoiselle - Id null

I'm setting up auditing on a project with JSF + Hibernate + Demoiselle .

Class Item:

@Entity
@Cacheable(true)
@Table(name = "itens")
@EntityListeners(value = PersistenceAuditor.class)
@XmlRootElement
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public class Item {
   private static final long serialVersionUID = 1L;
   @Id
   GeneratedValue(strategy = GenerationType.AUTO)
   @Column(name = "id")
   private Long id;
   @LazyCollection(LazyCollectionOption.FALSE)
   @OneToMany(mappedBy = "item", orphanRemoval = true, cascade = {CascadeType.PERSIST, CascadeType.REMOVE})
   @JsonManagedReference(value="itemParam")
   private List<ItemParam> params;

ItemParam Class:

@Entity
@Cacheable(true)
@Table(name = "item_params")
@EntityListeners(value = PersistenceAuditor.class)
@XmlRootElement
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public class ItemParam {
   private static final long serialVersionUID = 1L;
   @Id
   @GeneratedValue(strategy = GenerationType.AUTO)
   @Column(name = "id")
   private Long id;
   @NotNull
   @ManyToOne
   @JoinColumn(name = "item_id", referencedColumnName = "id", nullable = false)
   @JsonBackReference(value="itemParam")
   private Item item;

No PersistenceAuditor:

@PostPersist
public void postPersist(Object object) {
... consome auditoria

And to save:

@Transactional    
public String insert() {
   this.itemBC.insert(this.getBean());
   return getPreviousView();
}

ItemBC

@BusinessController
public class ItemBC extends DelegateCrudExt<Item, Long, ItemDAO> {

Audit is persistent however with objects with id null as if it took the object before it was "comitative" and I would like the object already updated. Maybe because of the @Transactional.

Object output:

Item{"id":69,"params":[{"id":null,"valor":10.0"}]}
ItemParam{"id":3,"valor":10.0}

Where should be something like:

Item{"id":69,"params":[{"id": 3,"valor":10.0"}]}
ItemParam{"id":3, "item":69, "valor":10.0}

Any ideas to solve this?
