JavaFX 8 TableView ne se remplit pas à partir de ObservableList (non FXML)

Question

Je crois que j'ai cherché toutes les questions similaires, mais je ne vois toujours pas mon problème. Je remplis un ObservableList d'une base de données qui réussit par ma sortie de console. J'ai une configuration de plusieurs contrôleurs pour un projet d'école pour créer une application de planification. J'ai un contrôleur racine qui fonctionne comme borderPane, deux contrôleurs fonctionnels pour les rendez-vous et les clients qui sont tous Singleton, et un contrôleur DataView partagé qui ne doit pas permettre à chaque vue d'instancier son propre DataView. J'ai implémenté toString sur chacun des contrôleurs pour cracher ce que sont les valeurs et/ou les identifiants d'objets de chaque élément et tout semble s'aligner. Je ne peux pas pour la vie de moi comprendre pourquoi les ListView ou TableView ne produisent pas les données liées. Voici les données de vue que je suis en train de se lier à la fois ListView et TableView

    appViewController.setDataViewController(appointmentViewController.getDataViewController()); 

    System.out.println(this.dataViewController); 
    System.out.println(this.dataView); 
    System.out.println(appointmentViewController.toString()); 
    System.out.println(customerViewController.toString()); 
    System.out.println(appViewController.toString()); 

    rootPane = (BorderPane) appView; 


    scene = new Scene(rootPane); 
    scene.getStylesheets().add("/styles/Styles.css"); 

    primaryStage.setScene(scene); 
    primaryStage.show(); 
} 

I avez installé les CellValueFactories, etc. Qu'est-ce que j'oublie ici?

En DataViewController la structure de la scène est initialisée à partir du constructeur. L'utilisation de l'un des setters de cette classe modifie les champs, et non modifiez la scène en laissant le vieux ListView vide dans la scène mais en imprimant le nouveau contenant les éléments de la méthode toString.
