Description

The handleSubmit function in Tapestry.FormEventManager takes a domevent argument, which it expects is extended and has the stop() function. This works in Firefox since the event is already extended, but breaks in IE.

It looks like this was introduced in revision 919693 of tapestry.js on 3/6/2010 when around line 1250 "Event.stop(domevent);" was changed to "domevent.stop();".

The prototype recommendation is to call "Event.extend(domevent);" at the top of any callback bound using bindAsEventListener.
