내가 깊이 파고하지만 충분해야 다음과 같은 같은 리팩토링하지 않았다. 첨부 된 리스너와 제거 된 리스너가 올바르게 실행되었는지 다시 확인하십시오.

public class ChoiceCell extends ListCell<ChoiceModel> { 

    private Node root; 
    private ChoiceController controller; 

    public ChoiceCell() { 

     URL location = ChoiceController.class.getResource("ChoiceView.fxml"); 
     FXMLLoader fxmlLoader = new FXMLLoader(); 
     fxmlLoader.setLocation(location); 
     fxmlLoader.setBuilderFactory(new JavaFXBuilderFactory()); 

     try { 
      root = (Node) fxmlLoader.load(location.openStream()); 
      controller = (ChoiceController) fxmlLoader.getController(); 
     } catch (IOException ioe) { 
      throw new IllegalStateException(ioe); 
     } 
    } 

    @Override 
    protected void updateItem(ChoiceModel model, boolean bln) { 
     super.updateItem(model, bln); 

     if (model != null) { 
      controller.setModel(model); 
      setGraphic(root); 
     } else { 
      setGraphic(null); 
     } 
    } 
}
