[jboss-user] [JBoss Seam] - Re: Seam 1.3.0.ALPHA UI example doubt
Using a managed rather than detached entity causes the UOE to go away.
@Name("personAction")
| @Scope(ScopeType.CONVERSATION)
| public class PersonAction {
|
| @In(create=true)
| private EntityManager entityManager;
|
| private Person person;
|
| private Integer id;
|
|
| @Transactional
| public String update() {
| entityManager.joinTransaction();
| //entityManager.merge(person);
| entityManager.flush();
| return "Success";
| }
|
| @Transactional
| public Person getInstance() {
| if (person != null && entityManager.contains(person)) {
| return person;
| } else {
| entityManager.joinTransaction();
| person = entityManager.find(Person.class, id);
| return person;
| }
| }
|
| public Integer getId() {
| return id;
| }
|
| public void setId(Integer id) {
| this.id = id;
| }
|
| }
