I need an event to fire at a periodic 1 second rate as long as the app is
running.
I looked at the examples and found this (see Below):

I am pretty new to flex, so what got me puzzled is the "package". all I am
looking for is to use this timer function and create use the event listener
function to do my bidding. my code looks like this, but its a no go.


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
applicationComplete="TimerExample()" color="#060606"
backgroundGradientAlphas="[1.0, 1.0]" backgroundGradientColors="[#4B679F,
#4B679F]">




<mx:Script>

import mx.rpc.events.ResultEvent;
import mx.rpc.events.FaultEvent;
import mx.controls.Alert;
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.events.Event;


public function TimerExample():void
{
var delay:uint = 1000;
var repeat:uint = 300;
var myTimer:Timer = new Timer(delay, repeat);

myTimer.addEventListener(TimerEvent.TIMER, timerHandler);

myTimer.start();
}


publicprivate function timerHandler(e:TimerEvent):void
{
trace("We got here");

}

]]>
</mx:Script>

</mx:Application>



package {
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.display.Sprite;

public class TimerExample extends Sprite {

public function TimerExample() {
var myTimer:Timer = new Timer(1000, 2);
myTimer.addEventListener("timer", timerHandler);
myTimer.start();
}

public function timerHandler(event:TimerEvent):void {
trace("timerHandler: " + event);
}
}
}

Here tis...

Thanks Greg, worked like a charm!
