Hi!
I have made a service encapsulated inside a Class with a method like so:
public function load(url:String,responder:Function):void
{

_service.url = url;
var token:AsyncToken = _service.send();
token.addResponder(new mx.rpc.Responder(function (event:ResultEvent):void{
                    responder(event);
            _service.url=null;
            token = null;
    }, handleServiceFault));

}

Then, inside a command, I inject that service :

public class LoadPageCommand extends ModuleCommand
{

            [Inject]
    public var inEvent:PageEvent;
    [Inject]
    public var serviceLoader:EpodxLoaderService;

...

And inside my execute method call the load method from that service and set a handleComplete that 'll be called each time result is received :

override public function execute():void
{

service.load(inEvent.page.url,handleComplete);

}

public function handleComplete(event:ResultEvent):void
{ .... }

The reason why I want a callback function is to access my event payload which contains the Value objects I want to work on ...
I'm sure all I did is conceptually good ...

thanks

   I'm not sure it is good!

   Well, you can explicitly "hold" a command, or rather, make it async-friendly, using the

   commandMap.detain(this) and commandMap.release(this).

   Rather then using the callback to "hold" the reference.
