是否可以像在sublimetext2编辑器(sublimetext)中那样进行多项选择并同时更改它们？

我想找到装有一个场景中的垂直框节点FXMLoader感谢Node#lookup(),但我得到以下异常:

java.lang.ClassCastException: com.sun.javafx.scene.control.skin.SplitPaneSkin$Content cannot be cast to javafx.scene.layout.VBox

    public void start(Stage stage) throws Exception {
        AnchorPane page = (AnchorPane) FXMLLoader.load(Main.class.getResource("test.fxml"));
        Scene scene = new Scene(page);
        stage.setScene(scene);
        stage.show();

        VBox myvbox = (VBox) page.lookup("#myvbox");
        myvbox.getChildren().add(new Button("Hello world !!!"));
    }
}

fxml文件:

<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml" >
  <children>
