The stack trace indicates that you have a NumericSlider.mxml file. You should have one called NumericSlider.as for your component, and your test file should not have the same name.

I followed it pretty much from the documents on flex.org. But here is the wierd part. If I add the component using just mxml it works fine traces out the statement in the constructor , shows the component. But if I create the component using just as3 then it doest call the constructor. Further more if I add the component it goes into a infinite loop. cheers :) firdosh //MAIN MXML CLASS <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml <http://www.adobe.com/2006/mxml> " layout="absolute" creationComplete="init(event);" xmlns:FComponents="org.fcomponents.*"> <mx:Script> <![CDATA[ import org.fcomponents.Test; import mx.containers.Panel; import org.fcomponents.NumericSlider; import flash.events.Event; private function init(evt:Event):void{ trace("add"); var c:NumericSlider=new NumericSlider(); trace("call"); //addChild(c); // UNCOMMENT THIS FOR INFINITE LOOP //this.addChild(new NumericSlider()); //<FComponents:NumericSlider /> IF YOU ADD THIS STATETMENT BELOW IT WORKS FINE } ]]> </mx:Script> </mx:Application> //CUSTOM COMPONENT CLASS package org.fcomponents { import mx.core.UIComponent; import mx.controls.Button; import mx.controls.VSlider; import mx.controls.NumericStepper; import flash.events.Event; [Event (name="change" ,type="flash.events.Event") ] public class NumericSlider extends UIComponent { private var $stepper:NumericStepper; private var $slider:VSlider; private var $showSlider:Button; private var $valueChanged:Boolean; private var $value:Number=0; public function NumericSlider(){ super(); trace("NS Constructor"); $valueChanged=false; } override protected function createChildren():void{ super.createChildren(); if(!$stepper){ $stepper=new NumericStepper(); addChild($stepper); } } override protected function commitProperties():void{ super.commitProperties(); if($valueChanged){ $valueChanged=false; $stepper.value=$value; invalidateDisplayList(); } } override protected function measure():void{ super.measure(); $stepper.width=100; $stepper.height=22; } override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void{ super.updateDisplayList (unscaledWidth,unscaledHeight); } } }
