JavaFX-填充表视图-PropertyValueFactory不是有效的类型

Question

我遵循了该教程：https://docs.oracle.com/javafx/2/fxml_get_started/fxml_tutorial_intermediate.htm#CACFHDEJ

我的第一个TableView填充就好了。但是我在另一个阶段的第二个没有。 我收到错误：“ javafx.fxml.LoadException：PropertyValueFactory不是有效的类型。”每次。

myfxml类：

我看不到任何问题，并且以前在我的其他fxml类上都可以使用。有人可以帮忙吗？
