Labels: easytest (was: )
> Sorting fails when items in Array implement IEventDispatcher rather than
> extending EventDispatcher
> --------------------------------------------------------------------------------------------------
>
> Key: FLEX-17625
> URL: https://issues.apache.org/jira/browse/FLEX-17625
> Project: Apache Flex

> 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.

> Extend EventDispatcher rather than implementing IEventDispatcher (this makes
> the problem go away)
