The error seems to indicate the service cannot be found..
Is your Services.mxml in the same package as the Delegate?
Your Services.mxml is a ServiceLocator isnt it?
What does the top 4 or 5 lines of your service.mxml look like?
I dont think it really matters at this point as your service is not
found(so its not actually executing from the looks of it) but FWIW, this
is how I would/do, do it:
<mx:HTTPService id="ListContactsHS"
url="http://localhost:3004/webservice/list";
useProxy="false"
resultFormat="array"
/>
public class ContactListDelegate
{
private var responder : IResponder;
private var service : Object;
public function ContactListDelegate(responder:IResponder)
{
this.service =
ServiceLocator.getInstance().getHTTPService("ListContactsHS")
this.responder = responder
}
public function list():void
{
this.service.send().addResponder(responder);
}
}
In my Command I would just call list();
Something like:
class MyCommand {
execute() {
x = new ContactListDelegate(this);
x.list();
}
result(){
// get the result here from the event object.
}
fault(){
//handle a fault.
}
//end class
}
HTH.
