Buggy source:
public UserDialog(User user,UserHandler userHandler){
  this.userHandler=userHandler;
  IdentityValueProvider<DeviceEventType> identity=new IdentityValueProvider<DeviceEventType>();
  final CheckBoxSelectionModel<DeviceEventType> selectionModel=new CheckBoxSelectionModel<DeviceEventType>(identity);

    }
  }
,200,i18n.event());

  columns.add(selectionModel.getColumn());
  columns.add(nameCol);

  notificationEventStore.addAll(Arrays.asList(DeviceEventType.values()));
  uiBinder.createAndBindUi(this);

  }
  email.addValidator(new RegExValidator("String_Node_Str",i18n.invalidEmail()));

Fixed version (ground truth):

  this.userHandler=userHandler;

    @Override public String getValue(    DeviceEventType object){
      return i18n.deviceEventType(object);
    }
  }
,200,i18n.event());
  List<ColumnConfig<DeviceEventType,?>> columns=new ArrayList<ColumnConfig<DeviceEventType,?>>();
  columns.add(selectionModel.getColumn());
  columns.add(nameCol);
  columnModel=new ColumnModel<DeviceEventType>(columns);
  view=new NoScrollbarGridView<DeviceEventType>();
  view.setAutoFill(true);
  view.setStripeRows(true);
  notificationEventStore=new ListStore<DeviceEventType>(new EnumKeyProvider<DeviceEventType>());
  notificationEventStore.addAll(Arrays.asList(DeviceEventType.values()));
  uiBinder.createAndBindUi(this);
  grid.setSelectionModel(selectionModel);
  grid.getView().setForceFit(true);
  grid.getView().setAutoFill(true);

  }
  if (ApplicationContext.getInstance().getUser().getAdmin()) {
    admin.setEnabled(true);
  }
