      Please help me

       

      This is my Code

       

      public ExtendedTableDataModel<Empleado> getEmpleadoDataModel() {

             if (empleadoDataModel == null) { 

                  empleadoDataModel = new ExtendedTableDataModel<Empleado>(new DataProvider<Empleado>() {

       

                              private static final long serialVersionUID = 1L;

       

                              public Empleado getItemByKey(Object key) {

                                 

                                for (Empleado e : empleados) {

                                  

                                      if (key.equals(getKey(e))) {

                                          return e;

                                      }

                                  }

                                  return null;

                              }

       

                              public List<Empleado> getItemsByRange(int firstRow,    int endRow) {

                                  return empleados.subList(firstRow, endRow);

                              }

       

                              public Object getKey(Empleado item) {

                                  return item.getEmplId();

                              }

       

                              public int getRowCount() {

                                  return empleados.size();

                              }

       

                          });

              }

       

              return empleadoDataModel;

          }

       

      And this is the page
