Add transition blind to xml image gallery

1

Hi,
I’m able to add Photo transition to the image gallery, but when I change the transition to blinds, it doesn’t work. What is wrong with the code?

Code for Photo Transition
//------------------transition----------------------------\
//in order to hold transitions, it needs a mc to hold picLoader;
import fl.transitions.;
import fl.transitions.easing.;

var fullContainer:MovieClip = new MovieClip();
var tm:TransitionManager = new TransitionManager(fullContainer);
var trans_obj:Object = new Object();
** trans_obj.type=Photo;
trans_obj.direction=Transition.IN;
trans_obj.duration=1;
trans_obj.easing=None.easeNone;**
//------------------transition----------------------------\
var thLoader:Loader;
var picLoader:Loader;

var xml:XML;
var xmlList:XMLList; //treats XMLlist as an array
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.load(new URLRequest(“data/images.xml”));

xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);

// use name property to connect thumbnail images to full size images
function xmlLoaded(e:Event):void {
xml = XML(e.target.data);//xml as XML
xmlList = xml.children();

for (var i:int=0; i < xmlList.length(); i++) {
    thLoader = new Loader();
    thLoader.load(new URLRequest(xmlList*.attribute("thumb")));
    thLoader.x = 25;
    thLoader.y = i * 75 + 25; 
    thLoader.name = xmlList*.attribute("source");
    addChild(thLoader);
    thLoader.addEventListener(MouseEvent.CLICK, showPic);
}

}

//click thumbnail and show picture;
function showPic(e:MouseEvent):void {
picLoader = new Loader();
picLoader.load(new URLRequest(e.target.name));
picLoader.x = 100;
picLoader.y = 25;

addChild(fullContainer);
fullContainer.addChild(picLoader);
tm.startTransition(trans_obj);

}

===============================================
the only difference for the blinds transition I made are

** trans_obj.type=Blinds;
trans_obj.direction=Transition.IN;
trans_obj.duration=2;
trans_obj.easing=None.easeNone;
trans_obj.numStrips=12;
trans_obj.dimension=1;**
