RE: [flexcoders] Debugging Event Bubbling

Your TweetCommEvent's clone method returns a PreferencePaneEvent rather than 
the TweetCommEvent I'd expect, at least in the code you wrote below.
It's not that, is it? 

public class TweetCommEvent extends Event
{

................
        override public function clone():Event {
                  return new PreferencePaneEvent(type, bubbles, cancelable);
         }
..............

}

Hi Folks,

I'm currently working on a twitter AIR client using the twitterscript AS3 
library and having some issues with bubbling custom events that are created by 
nested "classses" back to the main application.

I've architected so that the main application (A) spawns a new timeline window 
(B) for every twitter account a user may have. I have a Comm class (C) i use as 
a DAO layer to decouple the twitterscript custom events from my framework (in 
case i switch to a different as3 API library)

My custom event class looks like this 

package com.kubeworks.events
{
import flash.events.Event;

public class TweetCommEvent extends Event
{
public static const TIMELINE_BACK:String = "timelineBack";
public static const STATUS_BACK:String = "statusBack";
public static const USER_INFO_BACK:String = "userInfoBack";
public static const RATE_LIMIT_STATUS:String = "rateLimitBack";
public var data : Object = new Object ();

public function TweetCommEvent(type:String, bubbles:Boolean=true, 
cancelable:Boolean=false)
{
super(type, bubbles, cancelable);
}

override public function clone():Event {
return new PreferencePaneEvent(type, bubbles, cancelable);
}

}
}

My Comm Class goes something like
package com.kubeworks.data
{
// Twitter API calls
import com.kubeworks.events.TweetCommEvent;

import flash.events.Event;
import flash.events.EventDispatcher;
import flash.utils.*;

import mx.utils.ObjectUtil;

import twitter.api.Twitter;
import twitter.api.events.TwitterEvent;

public class TweetComm extends EventDispatcher
{

private var username:String;
private var password:String;

private var _twitterClient:Twitter;

// Constructor
public function TweetComm(usern:String, pass:String)
{
// Initialize Twitter Event Listeners
_twitterClient = new Twitter();
_twitterClient.addEventListener(Event.ACTIVATE, twitterClientActivateHandler);
_twitterClient.addEventListener(Event.DEACTIVATE, twitterClientDeactivate);
_twitterClient.addEventListener(TwitterEvent.ON_FRIENDS_TIMELINE_RESULT, 
twitterTimelineBack);
_twitterClient.addEventListener(TwitterEvent.ON_SET_STATUS, twitterStatusBack);
_twitterClient.addEventListener(TwitterEvent.ON_SHOW_INFO, twitterUserBack);
_twitterClient.addEventListener(TwitterEvent.ON_RATE_LIMIT_STATUS, 
twitterRateLimitBackHandler);


// Do stuff
setLogin(usern, pass);
setAuth();
}

and within that class i'm re-dispatching like:

private function twitterRateLimitBackHandler(event:TwitterEvent):void {
var eventObj:TweetCommEvent = new 
TweetCommEvent(TweetCommEvent.RATE_LIMIT_STATUS, true);
eventObj.data = event.data;
dispatchEvent(eventObj);
trace(">>twitterRateLimitBackHandler");
trace(ObjectUtil.toString(event));
trace("<<twitterRateLimitBackHandler");
trace(ObjectUtil.toString(eventObj));
}

I've set the bubbling to true. However in my main application this 
EventListener never fires

systemManager.addEventListener(TweetCommEvent.RATE_LIMIT_STATUS, 
onRateLimitHandler);

Any help would be greatly appreciated as i am out ideas and have exausted 
google and my flex friends.

Thanks,
Sean
