Major Description
on 11/27/2007 (rev 598811?), mknopp introduced two new js methods in wicket-event.js. This code causes javascript errors (on IE6) with the onload script. Other events on the page are fine, but (at least) the onLoad event uses the window object and IE issues the message "Object doesn't support this property or method".
Specifically, I traced the problem to line 97: element.getAttribute("id"). getAttribute() is not supported by the window object.
