Running my app returns me : Javafx.fxml.LoadExeption

Question

I have an issue with my app. I'm trying to make an app that works perfectly fine with the command prompt but with a nice interface to get a better user experience. To do so I chose Javafx that looks better than swing to me.
But it do not work. I don't understand what's wrong. Here is my Main app code :

package ch.makery.adress;

import java.io.IOException;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.scene.Parent;


public class MainApp extends Application {



    @Override
    public void start(Stage stage) throws Exception {
        Parent parent = FXMLLoader.load(getClass().getResource("PersonOverview.fxml"));
        Scene scene = new Scene(parent);
        stage.setTitle("Appication Extraction et remplissage Excel");
        stage.setScene(scene);
        stage.show();


}
}

Could you help me with it ?

You get a NullPointerException in your initialize() method. That is because your ComboBox methode is declared static.

The FXML injection does not work with static variables in JavaFX8.

If I delete the static declaration it returns me an errors and can't run the app. How could I get the value of my TextField and Combobox as a Variable that I can use ? — David, Sep 02 '15 at 09:06
No I can't compile it with errors it says Cannot make a static reference to a non-static field — David, Sep 02 '15 at 09:14
You're better off removing the text field and combo box value setting outside of your initialise method. Code to come shortly. — Draken, Sep 02 '15 at 09:15
What do you mean by removing Textfield ? Because I need them ! What I need is to get the content of the Textfield and put it in a global variable that I can use for an event for exemple. — David, Sep 02 '15 at 09:18
You're doing it at the wrong, point, hang on a second, I'll add my code in. You're trying to access them when they haven't been created yet and JavaFx then falls over — Draken, Sep 02 '15 at 09:19
@Moh-Aw what did you change except the static identifiers on the combobox Method ? Because just doing it do not work for me — David, Sep 02 '15 at 09:23
you need to remove the static identifier of the methode `afficheALL()`, too. That should make it work. I removed all static identifiers and replaced them with `private` as I cannot see, by the code given, why they should be static. — Moh-Aw, Sep 02 '15 at 09:28

Draken · Answer 2 · 2015-09-02T09:31:14.773

Try this in your MainApp class:

@Override
public void start(Stage stage) throws Exception {
    FXMLLoader loader = new FXMLLoader(getClass().getResource("PersonOverview.fxml"));
    Parent parent = (Parent)loader.load();
    Scene scene = new Scene(parent);
    stage.setTitle("Appication Extraction et remplissage Excel");
    stage.setScene(scene);
    stage.show();
    ((HexaController)loader.getController()).initForm();
}

Then in your controller have a method called initForm() that does this:

public void initForm(){
    list.add(new String("OUI"));
    list.add(new String("NON"));
    hexa.setItems(list);
    nombre.add(new Integer(0));
    nombre.add(new Integer(1));
    nombre.add(new Integer(2));
    nombre.add(new Integer(3));
    nombre.add(new Integer(4));
    nombre.add(new Integer(5));
    methode.setItems(nombre);
}

Also delete your static declarations in your controller, they aren't needed. You can call the method what ever you fancy, just make sure you use the method after you call stage.show();

It's not required for JavaFX. Is there another reason why you are using it? You should be safe to remove it if you only used it to call that initialise method — Draken, Sep 02 '15 at 09:35
Did not work without brings me errors when running it. But no matter the replacement of all the static by private make it works. Thanks — David, Sep 02 '15 at 09:36

Running my app returns me : Javafx.fxml.LoadExeption
