IE7 & I8 report: 'handler' is null or not an object

Reported by O'Shaughnessy Evans | October 25th, 2008 @ 02:15 AM

I get this message in IE7 and IE8 (haven't tried others) when accessing a web site that uses Prototype

Line: 3965
Error: 'handler' is null or not an object

This is in the createWrapper() function. If I change line 3965 in prototype.js from this:

handler.call(element, event)

to this:

if (handler) handler.call(element, event)

the error goes away. I didn't debug why the error is even occurring, but I can dig into the web site code to track it down if that's important.
