JavaFX Scene builder freezes (and then crashes) when adding ContextMenu on a button

Question

I have a problem with Scene Builder. I want to add ContextMenu on a Button. When I drag and drop the ContextMenu on a Button, it works fine (it appears in the Hierarchy tab). But when I click on the pre-defined MenuItem (under the ContextMenu) in the Hierarchy tab, Scene Builder freezes and I have to shut it down.

Could someone please help me with it? I know that I can create a ContextMenu in Java code, but i wanted to do it in Scene Builder (I want to make the ContextMenu pop up when you hover over the Button, so I also somehow need to edit it's trigger - could someone please tell me how to do it?).

there is the crash

I am using Java 13 and Scene Builder 11. As you can see, the program is not responding.

I appreciate any help. Thanks.

EDIT: This is what i got from EventViewer. I also looked in Scene Builder and according to 'About JavaFX Scene Builder', there should be a log file called scenebuilder-11.0.0.log (C:\Users\ZD\AppData\Local\Temp\scenebuilder-11.0.0.log). But there is no log file (even searching in file explorer did not find anything).

@FXML private AnchorPane mainPanel;
@FXML private AnchorPane blackPanel;
@FXML private ContextMenu popup;

public void initialize() {
    choiceBox.setItems(FXCollections.observableArrayList("Výběr1", "Výběr2", "Výběr3", "Výběr4", "Výběr5"));
    gc = canvas.getGraphicsContext2D();

    double x = backBtn.getTranslateX();
    double y = backBtn.getTranslateY();

    tt = new TranslateTransition(Duration.seconds(5), backBtn);
    tt.setToY(-200);
    tt.setToX(-100);

    tt.play();
    tt.setOnFinished((ae) -> {
        backBtn.setTranslateX(x);
        backBtn.setTranslateY(y);
    });

}

@FXML
private void handleButton() {
    mainPanel.setVisible(false);
    blackPanel.setVisible(true);
}

@FXML
private void backBtnClick() {
    tt.stop();
    mainPanel.setVisible(true);
    blackPanel.setVisible(false);
}


@FXML
private void canvasClicked(MouseEvent me) {
    gc.fillOval(me.getX() - 15, me.getY() -15, 30, 30);
}

@FXML
private void mouseDrag(MouseEvent mde) {
    gc.fillOval(mde.getX() - 15, mde.getY() - 15, 30, 30);
}

}

Answer 1

The same issue here, I found a non-perfect solution, try to remove fx:controller from the fxml file and open Scene builder as Administrateur.
