Working with list, duplicate element issue

[Rafael Ochoa: Flex Air Venezuela]

I was working with a List when the order is changed to increase the
elements of the list, no matter as the "data". got the solution for
this is the place dragCompleteEvent a listener to use the property as
event.currentTarget new data provider for the list, clearing the list
data, before reinitialize the List.


I hope this will help anyone with this problem.
