UI Sortable receive function not being called

UI Sortable receive function not being called


I am trying to grab the id of a sortable div when it's dragged over. I
cannot get the receive function to work:
$("#sortable1, #sortable2").sortable({
    receive: function(event,ui) {alert("received "+ $(ui.item).attr
('id')); },
connectWith: ['.connectedSortable']
});
I was able to get it working using the following code, however I could
not get ui.item to work, and when I try $(this) it returns the
sortable element and not the dragged div.
$('#sortable1').bind('sortreceive', function(event, ui) {
        var testing=$(this).attr('id');
        alert("got one "+testing);
    });
