Bonsoir, je suis sur un projet avec JavaFX et j'ai quelques erreurs. J'ai lu les réponses à des questions similaires, mais aucune des solutions ne semble fonctionner. J'espère sincèrement pouvoir trouver de l'aide. Voici le code:

C'est mon problème, j'espère avoir de l'aide bientôt.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

loader.setController(new ListController());

Pourquoi est-ce que tu specifies un controller dans ton code alors que tu en as déjà un qui est déclaré dans ton FXML ?
