Using Document.get().getElementById() returns an element, but it has
no value:
Element el = Document.get().getElementById("username");
if (el != null)
GWT.log("element: "+el.getNodeValue(), null);
prints only "element: " in the console.
Right now I'm having bigger problems trying to do things by
http://code.google.com/p/google-web-toolkit-incubator/wiki/LoginSecurityFAQ

When the logon is successful, I hide the logon RootPanel <div>, show
the application RootPanel <div>, and add my widget to the application
<div>. This works fine in Firefox and Safari, but in IE7, I get a
blank browser. The application <div> never shows.
Whoever wrote the LoginSecurityFAQ, it's time "TODO: Expand on this
section" on the auto-complete section. :)
