Передача открытие второго окна по нажатию на кнопку в первом окне
Пытаюсь реализовать открытие второго окна по нажатию на кнопку в первой форме, но получаю ошибку. Что не так делаю?
Контроллер первого окна:

sortedList.comparatorProperty().bind(tabLu0.comparatorProperty());
if (sortedList.size() != 0) {
tabLu0.setItems(sortedList);
}
}
private SortedList<Lu> getSortedListLu() {
return sortedList = new SortedList<Lu>(luService.getLuList());
}

fxmlLoader.setController(directoryAddWindowController = new DirectoryAddWindowController((DirectoryWindowController) this));
