The PureMVC Framework Code at the Speed of Thought

Hi all,

I need some help about using external classes to the framework:

I have a helper class that I use to connect to the database with amfphp 1.9. I need to retrieve a proxy property within that class. I import the following classes:

   import org.puremvc.as3.interfaces.IProxy;
   import org.puremvc.as3.patterns.proxy.Proxy;
   import org.puremvc.as3.patterns.facade.*;
   import com.xyz.project.ApplicationFacade;
   import com.xyz.project.model.ConfProxy;

and within the class I call the proxy:

   private var _confProxy:ConfProxy;

   public function amfWrapper():void {
      _confProxy = facade.retrieveProxy( ConfProxy.NAME ) as ConfProxy;
      gatewayURL = _confProxy.amfphp_gateway;
   }

As the helper class is not a proxy, the facade is not implemented and I have the following error:

   1120: Access of undefined property facade

What is the right way to retrieve proxy or mediator properties within an external class?

Many thanks for your help...
