Hi again,
Im trying to create a business delegate class for handling a connection
to, for example, an xml socket.
When trying to delegate onXML to the responder it keeps on saying there
is not such property on the responder, but of course there is. If I
define the function inside de business delegate class, it works
(changing responder.myOnXML for myOnXML, of course)
I have something like this on my command class:
class org.nevis.cairngorm.prexon.commands.SubscribeCommand implements
Command, Responder {
public function execute( event:Event ) : Void {
var delegate: SubscriberDelegate = new SubscriberDelegate( this );
delegate.subscribe( );
}
public function myOnXML( event : Object ): Void {
mx.core.Application.alert("RESPONDER OK");
}
..
}
And the business delegate has:
....
this.responder = responder; (the parameter for the class)
myListener.onXML = Delegate.create( responder, responder.myOnXML );
...
What Im I doing wrong? Is it okay setting a responder here? Cause I have
to define a result and fault handler im never using for this kind of
services...
