Question

我有ListView个留言。当我点击ListView中的邮件时，我想打开一个新窗口。由于某种原因，.fxml文件无法加载，我似乎无法找出原因。我怀疑我忽略了什么。

@FXML
private void handleSentMsg(MouseEvent event){
    String content = sentLvw.getSelectionModel().getSelectedItem().getContent();
    Profile receiver = sentLvw.getSelectionModel().getSelectedItem().getReceiver();
    Profile sender = sentLvw.getSelectionModel().getSelectedItem().getSender();
    GregorianCalendar gc = sentLvw.getSelectionModel().getSelectedItem().getTimestamp();
    try {
        FXMLLoader fxmlLoader4 = new FXMLLoader(getClass().getResource("ReceivedMsg.fxml"));
        Parent root4 = (Parent) fxmlLoader4.load();
        Stage stage4 = new Stage();
        // Lock ApplicationController, NewMsg needs to be closed first.
        stage4.initModality(Modality.APPLICATION_MODAL);
        stage4.setTitle("Ontvangen bericht van ");
        stage4.setScene(new Scene(root4));
        // Data meegeven aan de nieuwe controller.
        ReceivedMsgController controller4 = fxmlLoader4.<ReceivedMsgController>getController();
        controller4.setGc(gc);
        controller4.setContent(content);
        controller4.setSender(sender);
        controller4.setReceiver(receiver);
        stage4.show();
    }catch (Exception e){
        System.out.println("Can't load new window!");
    }
}

调试器退出此行：

Parent root4 = (Parent) fxmlLoader4.load();

ReceivedMsg.fxml文件：

完整的堆栈跟踪，但是在执行try catch时显示不多：

感谢您已经投入的时间，请告诉我是否需要提供更多信息。我真的很想知道为什么这不起作用。
