Yes, i saw this answer Passing Parameters JavaFX FXML. But it's not working.

setDayParting works from Controller Nº1 but when i'm call updatePreview in Controller Nº2 the parameter what i passed is not there. Why this don't work?

  • Passing parameters in Controller Nº1:

    private void giveParameterToController() {
    FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource(Main.newFileScreenFile));
    NewFileScreenController newFileScreenController;
    try {
        Pane pane = fxmlLoader.load();
        newFileScreenController = fxmlLoader.getController();
        newFileScreenController.setDayParting("Working");
        myController.setScreen(Main.newFileScreen);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

  • Controller Nº2:

public void setDayParting(String parting){
    dayParting = parting;
    System.out.println(dayParting);
}

private void updatePreview(){
    System.out.println(dayParting);
}

output:
Working
null

    When is `updatePreview()` called? Do you ignore the value stored in your `pane` variable on purpose? – fabian Aug 08 '16 at 06:10
  • @fabian If i don't do the pane thing i cant have access to the controller, the updatePreview is called when I'm in the screen of controller 2. – exsnake Aug 08 '16 at 06:14

    But in this case simply invoking `fxmlLoader.load()` without the assignment would also work. Furthermore, if you do not show this `Pane` either from the loading method or from the controller's `initialize` method, you probably use different scenes with different controller instances for displaying and for setting the data. – fabian Aug 08 '16 at 06:25
  • @fabian remove it but i still getting different instances of the controller... – exsnake Aug 08 '16 at 06:56

    You need to pass the data to the controller that is created when you load the `Pane` that is actually shown on screen... – fabian Aug 08 '16 at 07:13
  • @fabian solved it, thanks you for the information. – exsnake Aug 08 '16 at 08:07
