如何为整个GWT页面手动重置HTML？

我有一个MyArticlePresenter.java（在客户端包中） . 它的网址是“mydomain.com＃！article”：

MyArticlePresenter.java有一个RPC来调用文章 . 我希望在从数据库获取articleData后，它将清除该GWT页面中的所有内容，然后将整个GWT页面重置为新的 <html>

private AsyncCallback<GetArticleResult> getArticleCallback=new AsyncCallback<GetArticleResult>(){
    @Override
public void onSuccess(GetArticleResult result) {
        String articleData=result.getArticleData;

        RootPanel.getBodyElement().setInnerHTML("<html>"+articleData+"</html>");

    }
}

但是，我收到了一个错误 .

你能找到一个优雅地重置整个GWT页面的方法吗？

    看来这是解决方案：

    Scheduler.get().scheduleDeferred(new ScheduledCommand() {

                @Override
                public void execute() {
                    RootPanel.getBodyElement().setInnerHTML("<html>"+articleData+"</html>");
                }
          });
