Rails spinoffs - Feb 2006 - Sortable onUpdate problem

Hi,

I have two sortables with different options (but same tags. just
''li''). When I drag an item from sortable1 to sortable2 I want
it to
gain the options that the sortable2 items have.

I''ve tried all day to understand how Draggables and their observers
are destroyed but I keep gettting buggy behavior. Part of the problem
is the draggable and the draggableObserver are different. So
confusing! Droppables.add and Droppables.remove seem to work well.
Where is Draggables.add and Draggables.remove when I need them?

My idea is to use the onUpdate option of Sortables to call a function
that will delete and then recreate all of the draggables and
droppables with all the same options. My function and it''s various
attempt statements is below. Any ideas?

Thanks,
Peter

function homogenize(element, options){
  element=$(element);
	
	Sortable.findElements($(element), options).each(function(k){
	
	  Draggables.removeObserver($(k));
	  Draggables.unregister($(k));
	  Draggables.deactivate(k);

	  new Draggable(k,options);

	  Droppables.remove($(k));
	  Droppables.add(k, options);
	});
} // homogenize

what about just re-creating the sortables on update?

... onUpdate: function(sortContainer){
Sortable.create(...);
Sortable.create(...);
}

The sortables first get destroy (including the draggables) and then
re-created
