I’ve observed that editable ComboBox value not updated when default button is used. I mean that if user enters a new value in ComboBox and presses enter then he won’t get the value he has entered. If he clicks OK button using mouse then everything is OK. This my code:

public class JavaFxTest7 extends Application {

    @Override
    public void start(Stage stage) {
        var comboBox = new ComboBox<String>();
        comboBox.setEditable(true);
        var button = new Button("OK");
        button.setDefaultButton(true);

        button.setOnAction((e) -> {
            System.out.println("Value: " + comboBox.valueProperty().get());
        });
        var vBox = new VBox(comboBox, button);

        Scene scene = new Scene(vBox, 400, 400);
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }
}

If you run it and enter something in ComboBox and press enter you will see this output:

Value: null

I could fix it using this code:

button.setOnAction((e) -> {
    button.requestFocus();//<---- added
    System.out.println("Value: " + comboBox.valueProperty().get());
});

But it looks strange. Could anyone say how to fix this problem or maybe I am doing something wrong.
