    • Status: Resolved
    • Priority: P4
    • Resolution: Fixed
    • Affects Version/s: 8u40
    • Fix Version/s: 8u60
    • Component/s: javafx
    • Environment:

      Ubuntu 14.10

      java version "1.8.0_40"
      Java(TM) SE Runtime Environment (build 1.8.0_40-b25)
      Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

      Description

      When calling tableView.getSelectionModel().getFocusedIndex() an exception is thrown if the TableView is empty.

      To reproduce just run the example code:

      Example Code:


      package bugreports;

      import javafx.application.Application;
      import javafx.scene.Scene;
      import javafx.scene.control.TableView;
      import javafx.stage.Stage;

      import static javafx.application.Platform.runLater;

      public class TableViewNullPointerException extends Application {

          @Override
          public void start(final Stage primaryStage) throws Exception {
              final TableView<String> view = new TableView<>();

              primaryStage.setScene(new Scene(view));
              primaryStage.show();

              runLater(() -> view.getSelectionModel().getFocusedIndex());
          }
      }


      Workaround for now is something like this:

      int index;
      try {
          index = tableView.getSelectionModel().getFocusedIndex();
      } catch (NullPointerException e) {
         index = -1;
      }
