Hi Fay,
I've done the modification you told me but it's still not working... when i
insert new registers the pactId from assignedActivities remains null.
I copy the class activity with the modification:
@Entity
@Table (name="PROJECT_ACTIVITIES")
@SequenceGenerator(name = "SEQ_PACT_ID", sequenceName = "SEQ_PACT_ID",
allocationSize = 1)
public class Activity implements IsSerializable{
@Id
@Column(name="PACT_ID", nullable=false)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator =
"SEQ_PACT_ID")
private Integer id = null;
@Column(name="PACT_DESC")
private String desc = null;
@Column (name ="STATE")
private Integer state = null;
@Column (name ="PROJ_ID")
private Integer idProject = null;
@Column (name ="PACT_DUE_DATE")
private Date dueDate = null;
@OneToMany (mappedBy="activity", fetch = FetchType.LAZY)
@JoinColumn (name = "PACT_ID", nullable = false)
@Cascade({CascadeType.ALL,CascadeType.DELETE_ORPHAN})
private Set<AssignedActivity> assignedTo = new
HashSet<AssignedActivity>();
..}
Regards,
Eli
