Edited Issue: UpdatePanel Timeout issue? [27126]

Since we updated to the November 2011 build. Our users are receiving a Javascript error message, when the page is doing a async-postback update.


Error: [Exception... "'JavaScript component does not have a method named: "handleEvent"' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x80570030 (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)" location: "<unknown>" data: no]

Any one else having similar issues, or know of a solution?
