jQuery event handler

Description

Line 2965 in jquery.js:

var ret = handleObj.handler.apply( this, args );
if ( ret !== undefined ) {
	event.result = ret;
	if ( ret === false ) {
		event.preventDefault();
		event.stopPropagation();
	}
}

In my code, the value for handleObj.handler property sometimes becomes an array, and thus apply() doesn't work. I get error saying "handleObj.handler.apply() is not a function". Shouldn't there be a control statement, which would check whether handleObj.handler has apply() method assigned to it or not?

You can view my code at: http://shehi.dyndns.org/acp/components/ .

Press CREATE NEW under ''Subroutine Management''. Select ''Data-source=Module RDBMS ...''. Go to just-enabled ''Data-source'' tab; there select Fetch Criteria - Queries & Query Groups (Policies) = FETCH SELECTED. You will get the mentioned error... Check console for output...

_comment0:	In the console, I log '''event''' argument that is passed to Event-handler function, which is change-event in my case. All of the SELECTs in the use the same handler function, and if you check the objects in the console, you will see that '''handler''' property has a FUNCTION as value, which is correct. But when I "change" the SELECT of ''Fetch Criteria - Queries & Query Groups (Policies)'', I get '''handler = [all]'''. Shouldn't it be FUNCTION?! Why the value of SELECT is assigned to the handler property?! → 1313617758100200

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket! We do appreciate you providing the above link.

Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: http://jsfiddle.net/FrKyN/

Open the link and click to "Fork" (in the top menu) to get started.

@rwaldron: I can't give you reduced test case, because this particular situation only happens in 2 of my SELECTs I mentioned above. If I could narrow down the cause, I would've solved it myself :) I know it is weird, but we will have to dig into this dirty case using the example I provided... Sorry for being unhelpful :(

Guess this one won't get noticed because of my very big "sample", am I right? :( . I am open-source developer working on my CMS software, and I really would appreciate any help on this matter. My code is both in Google Code Eclipse Labs and Github. Thanks for any help in advance!

Sorry but there isn't enough information here to reproduce or check the bug. It's possible this is a dup of #9593 which should be fixed in 1.7.

I have the same bug in my app with Jquery 1.7.1

I attached change handler to input: text element.

And when text is changed there is this error (at least i when i try in firefox 9).

At other places in my code the handler works normally.

I've got the same problem using the latest version of JQuery.

@desi,

$('.subnav li .level-1').hover('touchstart', function(e) {

There is no signature of .hover() like this. Please ask for help on the forum or StackOverflow.
