Default Small BitmapData problem

Hello!
I have a sample code like this;
ActionScript Code:
private function createThumbs():void{         thumbsData = new ArrayCollection();         tempHolder.addChild(_32);         var bm:BitmapData = getBitmapData(tempHolder);     var img:Image = new Image();     img.source = new Bitmap(bm);     thumbsData.addItem(img);         tempHolder.visible = false;         testImg.source = new Bitmap(bm); }

I would like to populate thumbsData array collection with images for displaying them in some TileList. That same array collection in my example contains image and bitmap data but my testImg (which is Image class) is just white. Why is this happening?
Thanks for any help in advance!

Are you using an .xml file to refer to your images located in another folder?
Have you thought about using a custom item renderer, which can be used on any of the list controls?

Hi and thanks for help!
I am not using xml file, the whole thing is little more complicated.
_32 is actually an mxml file (component) and I would like to take a snapshot of that component. So, there is no actual file which I would like to capture. Components are instantiated in my application but the container that holds those components is rendering each one only when user wants to see them.
So, I'm trying to add a component to some 'temp' container, take a snapshot, put that snapshot in array collection, and finally make 'temp' container invisible.
I'm not sure if something like that is possible to do with itemRenderer?

Well, maybe show the getBitmapData()? It seems like nothing faulty in your code thus far.

Yeah, missing code for proper evaluation.

Another thing to look at is the object being drawn, needs to 'validateNow()' possibly before its ready to be drawn.

Of course, I will post needed code, I just thought this will be easy one =)
So, this is the function:
ActionScript Code:
private function getBitmapData(target:UIComponent):BitmapData{     var bd:BitmapData = new BitmapData(target.width, target.height);     var m:Matrix = new Matrix();     bd.draw(target, m);     return bd; }

@bowljoman:
In my case it could be something involved with validateNow()... I am working with FlexBook component and I'm not sure how to 'override' some of their methods of validating etc...
I also don't understand if tempHolder (which is Canvas) displays what I want (my component) and I try to get a copy of that and display it somewhere else it won't cooperate =)

Thanks for your help!!
