When i using Jquery update module, it will clash with Jquery UI .droppable() functionality.

Hi all,

In my local site i using Jquery update(6.x-2.0-alpha1), it will clash Jquery UI .droppable(6.x-1.4) functionality.

First i enabled Jquery UI module and i use .droppable() function to my drag & drop functionlity. All things are working fine until i enable Jquery update module. Once i enabled it, it will affect the drag & drop functionality. It cause the following error.

Error : inst is undefined in ui.dropppable.js(/jquery_ui/jquery.ui/ui/)

            var inst = $.data(this, 'droppable');
	    if(inst.options.greedy && $.ui.intersect(draggable, $.extend(inst, { offset: inst.element.offset() }), inst.options.tolerance)) {
	     childrenIntersection = true; return false;
	    }

Cause 1: I think Jquery update module will cause this error. Because after enabling this module only droppable function won't work.

Cause 2: I also think some Jquery, Jquery UI version won't support this droppable functionality.
I using the following version.
jQuery UI 1.6 version
jQuery Update 1.3.2 version

I also attached the error screen shot. It will help little bit to find the Cause and solution.

Can any one help me to find out solution.

Thanks & Regards
Sarav.
