bug: Widget _on shoud ignore extended Object.prototype

[rudygotya]

Hi,

when Object.prototype is extended, _on() breaks.

jsfiddle: ​http://jsfiddle.net/rudygotya/Y9veP/

fix:

diff --git a/ui/jquery.ui.widget.js b/ui/jquery.ui.widget.js
index 924d10b..80286ed 100644
--- a/ui/jquery.ui.widget.js

                $.each( handlers, function( event, handler ) {

+                       if( ! handler.hasOwnProperty( event ) ) {

                                // - disabled as an array instead of boolean

best regards

Sebastian

forget about the "fix" - sry. It has to be handlers.hasOwnProperty of course.

jQuery doesn't support modifying Object.prototype.
