2:45 p.m.
The environment is Tomcat 5.5.20 + Hibernate EM 3.3 + Seam 1.2.0 + Microcontainer. I'm
trying to build a simple clickable list with editing, everything works fine (querying,
updating), except when adding a new record:
UserBean.java
@Name ("userBean")
| @Scope (ScopeType.CONVERSATION)
| public class UserBean extends EntityController implements Serializable {
| @DataModelSelection
| @Out (required = false)
| private User selectedUser;
| @DataModel
| private List<User> users;
|
| public void addUser() {
| selectedUser = new User();
| }
| public void cancelEdit() {
| selectedUser = null;
| }
| @Factory ("users")
| @Begin (flushMode = FlushModeType.MANUAL)
| public void createRecords() {
| users = createQuery("SELECT u FROM User u").getResultList();
| }
| @Transactional (TransactionPropagationType.REQUIRED)
| public void saveUser() {
| persist(selectedUser);
| flush();
| addFacesMessage("User #{selectedUser.username} succesfully saved");
| createRecords();
| }
| public void selectUser() {
| }
| }
|

Has anyone been encountering similar problems before? Am I using the beans correctly?
Thanks,
