how to stop triggering two event at a time in spark textarea (as3+flex4)

Question

textChanged and valueCommit both event listener are attached with a spark textarea as follows:

addEventListener("textChanged", 
    function(event:Event):void {                                    
        colorize();                 
},false,0,true);

addEventListener("valueCommit",
    function(event:Event):void {                    
        colorize();                 
},false,0,true);

if I type any thing in textarea, then this colorize() function is called twice. How can I stop this one that both event should not be triggered together. Pls help

If you want to listen for typing, why do you have two listeners? If you really need two listeners, you need to queue colorize with a setTimeout instead of calling it directly:

import flash.utils.setTimeout;

private var colorizeQueued:Boolean = false;
private function queueColorize():void
{
    if (colorizeQueued)
        return;

    colorizeQueued = true;
    setTimeout(function():void
    {
        // Process for real and note update
        colorize();
        colorizeQueued = false;
    }, 100);
}


addEventListener("textChanged", 
    function(event:Event):void {                                    
        queueColorize();                 
},false,0,true);

addEventListener("valueCommit",
    function(event:Event):void {                    
        queueColorize();           
},false,0,true);
