FXMLLoader getController() returning null

So I'm new to JavaFx and programming in general, and I'm having a problem where I cannot get a fxml file Controller into my program. Here's the Code

@FXML
private void handleBtnAdicionarAction(ActionEvent event) throws IOException {   
    Stage adicionarStage = new Stage();
    FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/AdicionarWindow.fxml"));
    Parent root = (Parent) loader.load();
    Scene scene = new Scene(root);
    adicionarStage.setScene(scene);
    adicionarStage.centerOnScreen();
    adicionarStage.show();
    awUI = loader.getController();
    System.out.println(awUI);
    awUI.associarController(this);
}

After I do this the field awUI should contain the Controller of the file I'm loading but it comes out null... I've been doing other projects where I do this method and it's been working I don't know what may be Wrong here. Can someone Help me with this ?

Solution

  • If you are using IntelliJ mark your resources directory, by right clicking on the resource folder, selecting Mark Directory as -> Resources Root. Inside your resources folder there should be an fxml containing your AdicionarWindow.fxml file. If not using Intellij please check on how your IDE works with Resources folder.
