Hey Phil, Sure, let's go over ASyncToken and IResponder.
ASyncToken (http://livedocs.macromedia.com/flex/2/langref/mx/rpc/AsyncToken.html) >From the docs: This class provides a place to set additional or token-level data for asynchronous rpc operations. It also allows an IResponder to be attached for an individual call. The AsyncToken can be referenced in ResultEvent and FaultEvent from the token property. So we capture the token/id of the remote call we're making by assigning it to an ASyncToken instance, and then we can attach classes that implement the IResponder interface as responders. var call:ASyncToken = op.send(); call.addResponder(myResponderClass); myResponderClass must be an instance of a class that implements the IResponder interface (http://livedocs.macromedia.com/flex/2/langref/mx/rpc/IResponder.html). IResponder dictates that your class contains a result() method and a fault() method. These methods (at least the appropriate one depending on the success of your request) will be automatically called by the ASyncToken when the remote call returns. The parameter for both methods is of type object, but what is returned from a web service call is either ResultEvent or FaultEvent, so you'll generally cast it inside the method. This approach allows you to have more than one object that will be called when your service returns if you so choose.
