Java FX Custom Cell Factory für Kombinationsbox

@FXML ComboBox<User> cmbUserIds;

Callback<ListView<User>, ListCell<User>> cellFactory = new Callback<ListView<User>, ListCell<User>>() {

    @Override
    public ListCell<User> call(ListView<User> l) {
        return new ListCell<User>() {

            @Override
            protected void updateItem(User item, boolean empty) {
                super.updateItem(item, empty);
                if (item == null || empty) {
                    setGraphic(null);
                } else {
                    setText(item.getId() + "    " + item.getName());
                }
            }
        } ;
    }
}

// Just set the button cell here:
cmbUserIds.setButtonCell(cellFactory.call(null));
cmbUserIds.setCellFactory(cellFactory);
