SWFLoader and custom Effect

Question

I am having an issue figuring out custom Effects that are based on playing a SWF.  When I try to play the custom effect on my Effect subclass, I get a message in the console that says we loaded the SWF but it does not in fact play on the UIComponent.  Could somebody take a quick peek at my code and let me know what they think?
package us.ks.lenexa.Graphics.Effects
import mx.controls.SWFLoader;
import mx.effects.EffectInstance;
/**This class holds out info about what the effect does.
public class RedGlowInstance extends EffectInstance
//the flash glow object
//[Embed(source="us/ks/lenexa/assets/flash/Red_glow.swf")]
//public var redglow:Class;
private var _redGlow:SWFLoader = new SWFLoader();
public function RedGlowInstance(target:Object)
_redGlow.source = "us/ks/lenexa/assets/flash/Red_glow.swf";
_redGlow.height = 80;
_redGlow.width = 80;
_redGlow.visible = true;
_redGlow.load();
super(target);
// Override play() method.
        override public function play():void {
            _redGlow.visible = true;
            super.play();
        // Override end() method class to stop the SWFLoader
        override public function end():void {
            //_redGlow.visible = false;
            super.end();
package us.ks.lenexa.Graphics.Effects
import mx.effects.Effect;
import mx.effects.EffectInstance;
import mx.effects.IEffectInstance;
/**This class defines a custom effect that is the basis for the
public class RedGlowEffect extends Effect
public function RedGlowEffect(target:Object=null)
super(target);
instanceClass = RedGlowInstance;
override public function getAffectedProperties():Array{
return [];
// Override initInstance() method.
       override protected function initInstance(inst:IEffectInstance):void {
           super.initInstance(inst);
package us.ks.lenexa.Graphics
import com.esri.ags.Graphic;
import com.esri.ags.geometry.Geometry;
import com.esri.ags.symbol.Symbol;
import flash.events.MouseEvent;
import us.ks.lenexa.Graphics.Effects.RedGlowEffect;
/**Class plays a red-glow swf effect when the user mouses over the graphic
public class GlowGraphic extends Graphic
//here we have our redGLow
public var redGlowEffect:RedGlowEffect = new RedGlowEffect(this);
public function GlowGraphic(geometry:Geometry=null, symbol:Symbol=null, attributes:Object=null, playRedGlow:Boolean = false)
super(geometry, symbol, attributes);
if(playRedGlow==true){
PlayRedGlow();
public function PlayRedGlow():void{
this.addEventListener(MouseEvent.ROLL_OVER, playRedGlowFunct);
this.addEventListener(MouseEvent.ROLL_OUT, stopRedGlow);
private function playRedGlowFunct(e:MouseEvent):void{
//redGlowEffect.duration = 10000;
//var g:GlowGraphic = e.target as GlowGraphic;
redGlowEffect.play([this]);
private function stopRedGlow(e:MouseEvent):void{
redGlowEffect.stop();

Thanks a lot again Shachar.

You guessed right Shachar. I'm using the param as unique identifier.
Now I'm saving the data in SEQUENCE_SETUP and retrieving it when needed from AEGP using AEGP_EffectCallGeneric().

 one more thing you could try (which could prove tricky) is to set a different default for that slider during the param_setup call.that would cause each instance of your effect to reset that param to a different value.
but that's all in theory.
i'm not even sure you get more than one param_setup call per session.
just throwing some ideas out there.
I had tried this before but Param setup is called only once when the effect is applied for the very first time.
But thanks a lot Shachar, your first idea works fine.
