Property "accessibleRole" does not exist or is read-only
我已经在互联网上搜索了一个修复程序，但似乎没有人在此之前收到此错误。
这是我的创建舞台的功能：
public static MainSceneController mainSceneController;
public MainSceneController changeToMainScene() throws IOException {
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("MainScene.fxml"));
Parent root = (Parent)fxmlLoader.load(); //im getting the error on this line
mainSceneController = fxmlLoader.getController();
Stage stage = new Stage();
stage.setTitle("Test");
stage.setScene(new Scene(root));
stage.show();
return mainSceneController;
}
修改
这是fxml文件：
