I am having problems with a very simple datatable.
Here is my code....
Bean
|
| @Name("usermanager")
| @Stateful
| @Scope(SESSION)
| @Restrict("#{identity.loggedIn}")
| public class UserManager implements UserManagerInterface {
|
| @In
| private User user;
|
| @In
| private Session inetworkDatabase;
|
| @Logger
| Log log;
|
| @DataModelSelection("users")
| @Out(required = false)
| private User selectedUser;
|
| @DataModel("users")
| private List<User> users;
|
| @Factory("users")
| public List<User> getUsers() {
|
| List<User> retUsers = null;
|
| try{
|
| if(user != null){
|
| Criteria criteria = inetworkDatabase.createCriteria(User.class);
|
| retUsers = criteria.list();
|
| }else{
|
| }
|
| }catch(Exception e){
|
| }
|
| return retUsers;
| }
|
| public void editUser(){
|
| log.info("**************************************** ");
|
| }
|
| @Remove
| public void destroy() { }
| }

Every thing is ok at startup...
But when i click on the slink, i get this...
|
| 14:56:56,515 ERROR [SeamPhaseListener] uncaught exception
| javax.el.ELException: javax.ejb.EJBException: java.lang.ClassCastException:
java.util.ArrayList cannot be cast to javax.faces.model.DataModel
|
|
Why is that?
I know this is a pretty easy question, my apologies, but any help would be really
appreciated...
Thanks
