Thanks. This works:
String name = ((InputElement)Document.get().getElementById
("username")).getValue();
Using a native function was no big deal, but this code seems cleaner.

I've followed the link above. What I have works excellently in hosted
mode, as well as in Firefox 3.5, and Safari 4--the browser's password
manager is triggered, and the user is logged in. However I've still
no luck with IE7 (and no Javascript error indicated).
Does IE have a problem with hiding/showing DIV's? The form behaves
properly. injectLoginFunction() works (see below), the doLogin()
method is called, and the user logged in (so says my server's
console). As you see below, on a successful login, the LOGIN_DIV in
the original panel is hidden, the APPLICATION_DIV is made visible, and
the application's MainWindowWidget is created and added to the
APPLICATION_DIV. (After a user logs off the server, the showLoginDiv
() method is called, and we start over.)
As I said, this works in hosted mode, Firefox 3.5, and Safari 4. In
IE, after the login completes, all I see is a blank browser, and
"Done" in the lower left message area (no JS error).
Is there another way to handle this that will work with IE?
