Javafx passing parameters before loading the fxml loader

Hi experts . I m trying to pass parameters to fxml loader before loading the controller to define the gui how it should look like and what it should include a.s.o.
I have a main container and after clicking on buttons this container is loading the data from fxml. like this:

@FXML
private StackPane acContent;
@FXML
private void btnSupplierOnClick(ActionEvent event) throws IOException {
  FXMLLoader fxmlLoader = new FXMLLoader();
  fxmlLoader.load(getClass().getResource(/view/application/supplier/ViewSupplierList.fxml").openStream());
  AnchorPane acPane = fxmlLoader.getRoot();
  ViewSupplierListController supplierListController = fxmlLoader.getController();
  // Passing data to the supplierListController
  supplierListController.setData(userNameMedia,rootPane,acContent,acMain);
  acContent.getChildren().clear();
  acContent.getChildren().add(acPane);
}

Open in new window

With the setData function i m passing values to the controller but this happens after the controller has been loaded.
After googling i found a solution here (1. Create a controller instance manually) but i didn t get it to work.
Any help to solve my problem?
Thank you in advance.

Did you use the first example? The second one is wrong, I think

Finally i got it. This is the code:
1)

private StackPane acContent;
@FXML
private void btnSupplierOnClick(ActionEvent event) throws IOException {
  FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/view/application/supplier/ViewSupplierList.fxml"));
  // Create a controller instance
  ViewSupplierListController supplierListController = new ViewSupplierListController(userNameMedia,rootPane,acContent);
  // Set it in the FXMLLoader
  fxmlLoader.setController(supplierListController);
  AnchorPane acPane = fxmlLoader.load();
  acContent.getChildren().clear();
  acContent.getChildren().add(acPane);
}

Open in new window

2) Remove the fx:controller= .....
in the fxml datei
3) Create a constructor:

public  ViewSupplierListController(UserNameMedia data, StackPane rootPane,StackPane acContent) {
         this.userNameMedia = data;
         this.rootPane = rootPane;
         this.acContent = acContent;

    }

Open in new window

The mistake i did was instead of
