Error on triggering event on an element with no handlers.

[lukasz.chelmicki@…]

on line 4691 there is :

4688: event.data = handleObj.data;
4689: event.handleObj = handleObj;
4690: 
4691: ret = ( (jQuery.event.special[ handleObj.origType ] || {}).handle || handleObj.handler )
4692:     .apply( matched.elem, args );

In this line there is no check if handler exists. My solution to that is:

4688: event.data = handleObj.data;
4689: event.handleObj = handleObj;
4690:
4691: var tmp_handler = ( (jQuery.event.special[ handleObj.origType ] || {}).handle || handleObj.handler );
4692: if (typeof tmp_handler === 'function') {
4693:   ret = tmp_handler.apply( matched.elem, args );
4694: }

I noticed this in version 1.7.2 but it exists in all version up to date.

Do you have an example of code that causes an error? Please create one in jsfiddle.

I'll give an example tomorrow at work.

I tried to reproduce this bug. but it may have been the result of too many recursions. I was passing events between two windows.

You can reject this ticket.
