FXML Загрузить исключение при вставке данных собственного класса в табличное представление

У меня снова проблема.Я пытаюсь понять FXML, и в настоящее время я использую «Руководство по освоению FXML» оракула «Создание адресной книги с FXML».Я довольно близок к концу руководства, но не могу решить проблему, возникшую со вчерашнего дня.Я хочу написать программу поддержки для моего отца, но я всегда получаю заявление:javafx.fxml.LoadException: Maintenance is not a valid type.Есть 3 класса, которые важны для этой проблемы, я думаю.Это будут мои "mainLayout.fxml", "FXMLDocumentController.java" и "Maintenance.java", поэтому я просто публикую их в этом порядке

insertwindow.fxml уже существует и прекрасно работает, поэтому я не буду публиковать его, чтобы сократить свое сообщение для main.java и моих файлов свойств 4.Надеюсь, кто-то может сказать мне, что я делаю не так снова.Спасибо за помощь!
