Question

I have a div

<div id="aDiv"></div>

When I try

 Window.alert(RootPanel.get("aDiv").toString());

I get the element however, just after the above statement, when I

alert(document.getElementById("aDiv"));

It returns a null.

Can someone explain the discrepancies?

GWT’s javascript code is loaded into iframe, therefore document doesn’t point to the actual root document. To access the root page in GWT’s native methods, you should use $doc instead of document and $wnd instead of window.
