interface draggable doesn't work with jQuery in another frame

[schalke04]

I have jQuery in an iframe called "ajax", and want to work with it in another iframe "digitize".

I mapped jQuery like this

$ = parent.framesajax?.window.$;

and now I try this

$("div.listitem", parent.framesdigitize?.document).Draggable({

The div elements are retrieved correctly. When Draggable is applied, it only reaches "draginit", and never "dragmove". When I set it up with jQuery in the same iframe, there is no problem at all.
