Q: 

JQuery sortable connectedlists - validate move?

When sorting between two connected lists, I want to validate the move from one list to the other - BEFORE the move is done.

Now, I'm using the 'receive' event, but that's triggered after the element is added to the new list. I need an event that is triggered after mouse goes up, and before element is added to the new list. Any ideas?
