[flexcoders] HTTPService token: a bug or by design?

[Tim Romano]

I've run into one bug in the mx.rpc.http.HTTPService class  in FB4 beta 
2   -- the AsyncResponder's onResult function fires *twice* unless you 
wire up a dummy eventhandler.  And so I am wondering if the following is 
not also a bug:

var myResponder : AsyncResponder= new AsyncResponder(onResult, onFault);
var token: AsyncToken;
token = send();
token.addResponder(myResponder);
function  onResult(e:ResultEvent , token:Object=null):void {}

The token parameter is always null in the onResult function. Isn't that 
parameter supposed to contain the token to which the Responder was added?

Thanks
