DispatchEvent tenta di fare il cast di un eventoCustom ad un evento che non c'entra

[Wentu]

Salve a tutti

Ho il seguente problema nel fare il dispatch di un customevent (cosa che ho fatto altre volte con successo, ma questa volta non capisca cosa non va):

Ho un customevent WSConnectorEvent extends Event


package
{
import flash.events.Event;
public class WSConnectorEvent extends flash.events.Event
{
public static const WSLOAD:String = "WSConnectorEvent_WSLOAD";
public static const WSLOADFAULT:String = "WSConnectorEvent_WSLOADFAULT";


public function WSConnectorEvent(type:String,bubbles:Boolean,cance lable:Boolean)
{
super(type,bubbles,cancelable);
}
override public function clone():Event
{
return new WSConnectorEvent(type,bubbles,cancelable);
}
}


}

La classe WSConnector tenta di contattare un webservice e in caso di successo o fallimento deve inviare un WSConnectorEvent di tipo WSLOAD o WSLOADFAULT

package
{
import mx.rpc.soap.*;
import mx.rpc.events.*;
import mx.rpc.AbstractOperation;
import flash.utils.getQualifiedClassName;
import flash.events.*;
import flash.events.EventDispatcher;


public class WSConnector extends EventDispatcher
{
private static var instance:WSConnector = new WSConnector();
private static var WSURL:String;
private var quizWebService:WebService;
private var serviceOperation:AbstractOperation;
public function WSConnector()
{
//...
}


public function SetupWebService():void
{
quizWebService = new WebService();
//movieWebService.loadWSDL(WSURL);
quizWebService.addEventListener(LoadEvent.LOAD, quizWebService_onLoad);
quizWebService.addEventListener(FaultEvent.FAULT, quizWebService_onFault);
quizWebService.loadWSDL(WSURL);
}


function quizWebService_onLoad(evt:LoadEvent)
{
var wsce:WSConnectorEvent = new WSConnectorEvent(WSConnectorEvent.WSLOAD, true,true);

dispatchEvent(wsce);
}

function quizWebService_onFault(evt:FaultEvent)
{
var wsce:WSConnectorEvent = new WSConnectorEvent(WSConnectorEvent.WSLOADFAULT, false ,false);

dispatchEvent(wsce);
}

}
}


-----------------------------------------
Quello che succede è che in entrambi i casi la variabile wsce di tipo WSConnectorEvent viene creata correttamente ma quando chiamo dispatchEvent(wsce) ricevo un errore del tipo che riporto sotto.

DOMANDA: perchè diavolo dispatchEvent cerca di convertire un mio evento a un evento che a questo punto non c'entra nulla ? Perchè dovrei dover ri-dispatchare un evento castabile a quello che sto gestendo ??

TypeError: Error #1034: Assegnazione di tipo forzata non riuscita: impossibile convertire WSConnectorEvent@1f7efa1 in mx.rpc.events.FaultEvent. (in english this approximately means Impossible to cast from WSConnectorEvent@1f7efa1 to mx.rpc.events.FaultEvent)

Grazie per il vostro aiuto

Thankx to maskedMan I now have the answer:

You're dispatching an instance of your custom event, but the function that you've set up to handle it expects a FaultEvent object. In brief, the scenario looks something like this:

foo.addEventListener(CustomEvent.CUSTOMTYPE, handleEvent); private function handleEvent(evt:FaultEvent):void{ }
