I have been fighting with a error that I just can't see why happens - so now I
ask you smart people.
I have a entitybean with a one to one connection to another entity bean.
When I try to change the username like this:
| Subscriber sub = (Subscriber) em.createQuery("...").getSingleResult();
| sub.setUserName("newusername"); //notice that
setUserName actually is getRoles().setUserName("newusername");
| sub.setPassword("newpassword");
| sub.getRoles().setRoles("newRole");
| //autocommit
|
I get the following exception:
13:01:46,730 INFO [MpSupport-web] signupStep1 error,
java.lang.RuntimeException: org.jboss.tm.JBossRollbackException: Unable to
commit, tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=nicolai/87,
BranchQual=, localId=87] status=STATUS_NO_TRANSACTION; - nested throwable:
(javax.persistence.PersistenceException: org.hibernate.HibernateException:
identifier of an instance of dk.niro.mpsuite.persist.SubscriberRoles was
altered from oldusername to newusername)
But why??
| @Entity
| public class Subscriber implements Serializable{
| ...
| @OneToOne(cascade={CascadeType.ALL}, optional=false)
| @JoinColumn(name="username", unique=true)
| public SubscriberRoles getRoles() {
| return roles;
| }
|
| public void setRoles(SubscriberRoles roles) {
| this.roles = roles;
| }
|
| public void setUserName(String username) {
| getRoles().setUserName(username);
| }
|
| @Transient
| public String getUserName(){
| return getRoles().getUserName();
| }
| }
|
| @Entity
| public class SubscriberRoles implements Serializable{
|
| private String userName;
|
| private String roles;
|
| public SubscriberRoles(){}
|
| public SubscriberRoles(String username, String roles){
| userName = username;
| this.roles = roles;
| }
| public String getRoles() {
| return roles;
| }
|
| public void setRoles(String roles) {
| this.roles = roles;
| }
|
| @Id
| public String getUserName() {
| return userName;
| }
|
| public void setUserName(String userName) {
| this.userName = userName;
| }
| }
