How to dispach a custom event inside httpservice result event - actionscript-3

Question

In my AIR application, I try to dispatch a custom event from a class to main window.
This class is use to call httpservice. My goal is to send a custom window when the httpservice result is send.
package fr.inter.DataProvider
{
import flash.events.Event;
import flash.events.EventDispatcher;
import fr.inter.config.urlManager;
import fr.kapit.introspection.components.DisplayListComponent;
import mx.collections.XMLListCollection;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.http.HTTPService;
[Event(name="evtPatSelect", type="flash.events.Event")]
public class sPatient
{
private var _phppaIndex:String;
private var _phppaNomU:String;
private var _phppaPrenom:String;
private var phpSearchPatNom:HTTPService;
public function sPatient()
{
}
public function sPhpSearchPat(p:Object):void
{
phpSearchPatNom = new HTTPService();
phpSearchPatNom.method="POST";
phpSearchPatNom.resultFormat = "e4x";
phpSearchPatNom.addEventListener(ResultEvent.RESULT,resultListePatient);
phpSearchPatNom.addEventListener(FaultEvent.FAULT,serviceFault);
var urlPhp:urlManager=new urlManager();
phpSearchPatNom.url = urlPhp.urlService() + "20SearchNom.php";
phpSearchPatNom.send(p);
}
private function resultListePatient( event:ResultEvent ):void
{
var xmlList:XMLList = XML(event.result).patientPHP;
var xmlListColl = new XMLListCollection(xmlList);
if(xmlListColl.length==1)
{
_phppaIndex = xmlListColl.getItemAt(0).paIndex;
_phppaNomU = xmlListColl.getItemAt(0).paNomU;
_phppaPrenom = xmlListColl.getItemAt(0).paPrenom;
var evtPat:Event = new Event("evtPatSelect");
var evdips:EventDispatcher = new EventDispatcher();
evdips.dispatchEvent(evtPat);
}
}
private function serviceFault( event:FaultEvent )
{
trace( event.fault.message );
}
public function get phppaIndex():String
{
return _phppaIndex;
}
public function set phppaIndex(value:String):void
{
_phppaIndex = value;
}
public function get phppaNomU():String
{
return _phppaNomU;
}
public function set phppaNomU(value:String):void
{
_phppaNomU = value;
}
public function get phppaPrenom():String
{
return _phppaPrenom;
}
public function set phppaPrenom(value:String):void
{
_phppaPrenom = value;
}
}
}
In main window I've added a eventlistener but this seems not works.
Can you help me to solve that?
Thanks

First, extend the sPatient class as an EventDispatcher
public class sPatient extends EventDispatcher {
Then, create a class for your custom Event
public class MyCustomEvent extends Event {
public static const CUSTOM_TITLE:String = "custom_title";
public var eventData:Object;
public function CustomEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, data:Object = null) {
super(type, bubbles, cancelable);
if(data != null) eventData = data;
}
public override function clone():Event {
return new CustomEvent(type, bubbles, cancelable);
}
public override function toString():String {
return formatToString("CustomEvent", "type", "bubbles", "cancelable", "eventPhase");
}
}
Then in your sPatient class, go:
this.dispatchEvent(new MyCustomEvent(MyCustomEvent.CUSTOM_TITLE));
And listen for it like so
sPatientInstance.addEventListener(MyCustomEvent.CUSTOM_TITLE,functionHandler);
