TileList redraw bug?

[alex-party]

Hi folks,
Is there any known bug with the TileList component?
Basically, I display thumbnails in the TileList component with custom
itemRenderer and It seems like after updating ArrayCollection with new values,
it receives values OK, but wont update the actual images.
Thank you in advance,
Alex

I'm having this problem as well. I have a bunch of thumbnails in TileList that
when i update the array and select a new set of thumbnails they do not refresh
with the correct set (the old thumbnails remain) but if I click on one of the
result thumbnails i do get the details for the updated (correct) image.

So like above it seems to receive all values ok but the thumbnail set does not
update.

Anyone know what might be causing this?

Thanks in advance

Paul

To reproduce the mentioned above problem, here is short example:

<mx:Application ... creationComplete="srv.send()">
<mx:Script>
<![CDATA[
[Bindable] public var imgs:ArrayCollection;
[Bindable] public var _url:String="vars.php";

private function srv_result(evt:ResultEvent):void {
var obj:Object=evt.result;
imgs=obj.start.imgs.image;
}

######### 1. lets say user pressed a button and invoked this function, which
populates new values into IMGS array.
######### 2. values received from srv_result() function are OK, but images
won't update in TileList component
public function xgo(name:String):void{ function.
srv.url=_url+'?name='+name; srv.send();
}

]]>
</mx:Script>

<mx:HTTPService id="srv" url="{_url}" result="srv_result(event)"/>
<mx:TileList dataProvider="{imgs}" itemRenderer="views.xImg" />

</mx:Application>

After digging more into code, I've found, that my itemRenderer component have
been loading images on "initialize" event once, then when ArrayCollection
changes, there is no "initialize" event happening anymore, that's why images
are not updating, so is there any way I could add event listener on TileList or
itemRenderer to trigger initialize event once more or force redraw it after
ArrayCollection changed?

=========== itemRenderer component ================
<mx:Canvas initialize="init()">
<mx:Script>
<![CDATA[
private function init():void{
var request:URLRequest = new URLRequest(
'assets/gallery/small/'+data.filename+'.jpg' );
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener( Event.COMPLETE, cropImage );
loader.load( request );
}
private function cropImage(event : Event):void{
....croping image here and loading into x_img.source.....
}
</mx:Script>
<mx:Image id="x_img" x="5" y="3"/>

</mx:Canvas>

Thanks,
Alex

Well, thank you all, but I found a solution to this problem myself and it seems
to be working. All I had to do is add dataChange event to the itemRenderer
component, like that:

=========== itemRenderer component ================
<mx:Canvas dataChange="init()">

I hope this will help someone,
Regards,
Alex
