> Steps to reproduce:
> 1.Create a class which implement IEventDispatcher (and delegates implementation to a
contained EventDispatcher), that exposes a single String property.
> 2.In either AIR or Flex, create some UI that displays an ArrayCollection of the class
built in step 1 and sort it based on the property exposed.
> 3.Add a button that changes the property of one of the objects bound in the view and
then refresh the ArrayCollection.
>  
>  Actual Results:
>  The following error is thrown:
>  Error: Find criteria must contain at least one sort field value.

>  Workaround (if any):
>  Extend EventDispatcher rather than implementing IEventDispatcher (this makes the problem
go away)
