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;
}
