It seems to me that the best approach here would be to simply grab the HTML
content on startup, pull it out using innerHTML, then throw it into a new
HTML widget that you can switch out with others. For example:
<...>
<div id='stuff'>
<... stuff ...>
</div>
<...>
Element stuffElem = Document.get().getElementById("stuff");
String html = stuffElem.getInnerHTML();
stuffElem.setInnerHTML("");
RootPanel stuffRoot = RootPanel.get("stuff");
HTML newStuff = new HTML(html);
stuffRoot.add(newStuff);
Then you can do whatever you want with the newStuff widget, including
replace it with other widgets.
