更新 MessageDialog 检票口的消息内容

Question

        //TrainingDialog associated with save button
        trainingDialog = new MessageDialog("trainingdialog", "Warning", "Message contents here",
                DialogButtons.OK, DialogIcon.WARN) {
            public void onClose(AjaxRequestTarget target, DialogButton button) {
                if (button != null && button.match(LBL_OK)) {
                    target.prependJavaScript("return saveClick()");
                    saveButton.add(new AttributeModifier("onclick", "return saveClick()"));
                    target.add(saveButton);
                    //note: predefined button text are:
                    //LBL_OK, LBL_CANCEL, LBL_YES, LBL_NO, LBL_CLOSE, LBL_SUBMIT
                }
            }
        }; 


        add(trainingDialog);

现在在我显示对话框之前使用 trainingdialog.open(目标)

有没有办法更新对话框的内容？

假设 MessageDialog 来自 Wicket JQuery UI 库，那么您可以执行 trainingDialog.setModelObject("New message")。
