Hi Jon,
Sprite extends EventDispatcher, so you don't need to instantiate another
EventDispatcher in your class.
Instead, try the following:
this.dispatchEvent(new Event("AuthenticationFailed",true,false));
If you still have problems can you let us know what object you are
creating your event listener on?

Subject: [flexcoders] how do you dispatch event from a custom class?
I have a custom class that I want to be able to
dispatch an event. However, it's not entering the
event into the event stream, I don't even think the
event is getting out of the class. I have bubbles set
to true. does anyone know how to get the event
entered into the event stream... the docs aren't very
explicit on this subject....
ie
code to call my class...
private function
handleLBResponse(eventObj:ResultEvent):void {
var tempArray:Array;
var checkResult:WebServiceCheck = new
WebServiceCheck();
if
(checkResult.checkServiceReturnStatus(eventObj,true))
{
tempArray =
mx.utils.ArrayUtil.toArray(eventObj.result.lbvServerTos);
if (tempArray.length > 1) {
dpLBVServerData.source =
tempArray;
} else {
dpLBVServerData.removeAll();
}
} else {
dpLBVServerData.removeAll();
}
}

code in the class

package comp.webconfig.services {
import flash.display.Sprite;
import mx.rpc.events.ResultEvent;

false):Boolean

var dispatcher:EventDispatcher = new

myRawMessage =
resultToCheck.result.requestMessage;

{
myRawStatus =

}
}
if (myRawStatus != null) {
switch (myRawStatus) {

// do something here
like popup a message
myMessage = "Sorry,
there was an error trying to
access the information you requested. \n\n"
myMessage +=
myRawMessage;

this was a successful addition
