Graham I see someone else answered your question, but... you might also want to look at Darron's page which talks about the Cairngorm Responder vs the Flex IResponder:
http://www.darronschall.com/weblog/archives/000234.cfm The onResult(event:* = null):void method you asked about tells me you're using/learning the "pure" Cairngorm architecture which employs a Cairngorm Responder to get the data from the Delegate/Service back to the initial Command. Darron's page explains an alternative, IResponder, that is already part of the Flex API. It does the same thing, but it's more flexible, simpler to use, and easier to understand (just my opinion). I'm using it in all my new Cairngorm apps. I have yet to find a reason not to.
