Hello, Just to let you know: The solution is to first make a copy of the Data Provider : (Assuming Data Provider is an ArrayCollection)
private var originalList:Array; originalList = List.dataProvider.toData().sclice(); Now you can make all the drag & drop ops you want... Afterward you just recreate your list once you want to 'reset' List.dataProvider = new ArrayCollection(originalList.slice() ); (Using slice ensure a softcopy and protects the original data) --- In [email protected], "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Setting sort must always be followed by refresh(), so what you tried > wont work.
