I am working with jQuery's sortable (jQuery ui)

By default `dropOnEmpty = true`, and as a *speedup* I'm applying the `connectwith` *after* I apply `.sortable()` to my selectors as follows:

```
<script type="text/javascript">  
  $('#selector1').sortable({ 
    over: function(ev,ui){
      console.log('Dragging over: '+$j(ui.placeholder).parent().parent().parent().attr('id'));
    } 
  )};  
  $('#selector2').sortable({ 
    over: function(ev,ui){
      console.log('Dragging over: '+$j(ui.placeholder).parent().parent().parent().attr('id'));
    } 
  )};

  $('.ui-sortable').sortable('option', connectWith', '.ui-sortable');
</script>

```

I've demonstrated my *logging* to try to figure out what's going on - Imagine I first drag from #selector1 to #selector2 (which is empty) - no logging appears, but than if I drag back into the source, I get the logging, and than when I drag back into the target column it works?

The empty selector even has `ui-sortable` class but it's not connecting!

How should I make sure that even the empty lists while applying the connect-with after initializing the the `connectWith` separately?
