NonUniqueObjectException

[subhash.bhushan]

Hi,

I am trying to use a OneToMany relationship between my MemberDetail Class and its addresses. Here is the code:

MemberDetail.java:

public class MemberDetail implements java.io.Serializable {
.
.
.
private Collection<Address> addresses = new ArrayList<Address>();
.
.
.
 @OneToMany(cascade={CascadeType.ALL}) @JoinColumn(name="LINKER_ID")
 public Collection<Address> getAddresses() {
 return addresses;
 }
 public void setAddresses(Collection<Address> addresses) {
 this.addresses = addresses;
 }
.
.
.

Address.java:

public class Address implements java.io.Serializable {
.
.
.
private int id;
.
.
.
@Id
@Column(name = "ID", unique = true, nullable = false, insertable = true, updatable = true)
 public int getId() {
 return this.id;
 }
 public void setId(int id) {
 this.id = id;
 }
.
.
.

The Address class does not have any reference to MemberDetail class.

Creating the Member Detail:

 memberDetail.setProfileId(profile.getProfileId());
 memberDetail.setStatus('R');
 memberDetail.setModificationNum(1);

 officeAddress.setActive('R');
 officeAddress.setModificationNum(1);
 personalAddress.setActive('R');
 personalAddress.setModificationNum(1);
 memberDetail.getAddresses().add(officeAddress);
 memberDetail.getAddresses().add(personalAddress);
 try {
 manager.persist(memberDetail);
 return true;
 }catch(Exception exc){
 exc.printStackTrace();
 return false;
 }

I get the following error upon persisting:

19:37:16,671 ERROR [STDERR] javax.persistence.PersistenceException: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.justbooks.common.entities.Address#0]

19:37:16,687 ERROR [STDERR] at com.justbooks.security.activities.ManageProfileBean.createProfile(ManageProfileBean.java:95)

I am using EJB 3.0 persistence with J2EE 1.4/J2SE 5. I assume that Address IDs should be autogenerated. I am using MySQL DB and I have marked the field for autogenerate.

I am sure I am doing something wrong, but not able to pinpoint the problem.

Thanks in advance. Any clues are welcome.
