Language Version: ActionScript 3.0

Runtime Versions: Flash Player 9, AIR 1.1

This error is thrown when retrieving an item from a collection view requires an asynchronous call. This error occurs when the backing data is provided from a remote source and the data is not yet available locally.

If the receiver of this error needs notification when the requested item becomes available (that is, when the asynchronous call completes), it must use the addResponder() method and specify an object that supports the mx.rpc.IResponder interface to respond when the item is available. The mx.collections.ItemResponder class implements the IResponder interface and supports a data property.
