Hi All

I have a problem in dispatching a customEvent. I already managed to dispatch custom events in other projects and all worked well so i can’t understand what’s different now.

I have a WSConnectorEvent that extends Event

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

}

```

The class WSConnector tries to reach a WebService and in the case of success or failure should send a WSConnectorEvent of type WSLOAD or WSLOADFAULT.

```auto

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);
        }
       
    }
}

```

* * *

what actually happens is that (in both cases) the variable wsce of WSConnectorEvent type is correctly created but when the dispatchEvent(wsce) is called, i receive the following error (in case of function quizWebService\_onFault(evt:FaultEvent) ).

Question: why on hell is it trying to convert my custom event in a mx.rpc.events.FaultEvent ??? Isn’t DispatchEvent accepting Event as a class ? Why does it need to cast it to something completely unrelated ???

Thank You very much !
