dataTable lastRecord and dataTable reRender Problem
Hi, all,
i have a problem can any one suggest me, because i am new to seam and richfaces,
The Problem is
when i am insert a record it is fine record is sucessfully inserted, and displaying in the dataTable, in the dataTable delete record it is fine to delete a record, when i am deleting the last record of the list its not reRender the page, if i am press the refresh button the record is not displaying, actually the last record is deleting but it is remains in dataTable. and also search the record in the column attribute "filterBy" the loader bar is searching every letter when i am typing, i dont want that, its not type safe, what i mean is when i typing stop in the search field and that time the record is retrieving and how do i do that
here is the action class
@Name("mobeeUserAction")
@Scope(ScopeType.CONVERSATION)
public class MobeeUsersAction{
@In
private EntityManager entityManager;
@In
private FacesMessages facesMessages;
@DataModel
private List<MobeeUser> mobeeUsersList;
@Logger
private Log _log;
@DataModelSelection
@Out(required=false)
private MobeeUser activeUsers;
private List<MobeeUser> mobee_user_list = new ArrayList<MobeeUser>();
@Factory("mobeeUsersList")
public void retrieveAllUsers(){
mobeeUsersList = entityManager.createQuery("select m from MobeeUser m order by m.firstName desc").getResultList();
}
@Begin(join=true)
public void add(MobeeUser mobeeUser){
entityManager.persist(mobeeUser);
activeUsers = mobeeUser;
facesMessages.add("#{activeUsers.firstName} your Registration is Successfull ");
retrieveAllUsers();
}
@Begin(join=true)
public void delete(){
if(mobeeUsersList.size()==0){
facesMessages.add("No Users");
}else{
_log.info("====Before delete list size==" + mobeeUsersList.size());
_log.info("======delete begin===");
activeUsers = entityManager.find(MobeeUser.class, activeUsers.getId());
entityManager.remove(activeUsers);
facesMessages.add("#{activeUsers.firstName} is deleted.");
retrieveAllUsers();
_log.info("======delete end=====");
_log.info("====After delete list size==" + mobeeUsersList.size());
}
}
}
