Flex :: Unable To Dispatch Custom Event In Mobile Application

I am trying to get some code working from an example I came across. most of the functionality works but it is failing when it tries to dispatch a custom event. At the moment the code that is trying to dispatch the event is inside a class that handles amf remoting.the example has this line in it for the dispatch:

Application.application.dispatchEvent(new
RemoteResultEvent(RemoteResultEvent.USER_UPDATE_COMPLETE,"test"));

but that fails as it does not know what application.application is "Multiple markers at this line:

-Access of undefined property application"

I assume that this is because this was not written for a mobile app. I tried changing the dispatcher to EventDispatcher

EventDispatcher(
new RemoteResultEvent(RemoteResultEvent.USER_UPDATE_COMPLETE, "worked"));

but I then get this error:

TypeError: Error #1034: Type Coercion failed: cannot convert events::RemoteResultEvent@18337731 to flash.events.EventDispatcher.

This is the code in the custom event RemoteResultEvent.as :

package events
{
import flash.events.Event;
public class RemoteResultEvent extends Event {

[code]...
