Lets try to add more info. Theres a TileList with a ItemRenderer. The
ItemRenderer code is:
<mx:Script>
<![CDATA[
import mx.core.Application;
import mx.collections.ArrayCollection;
[Bindable]
private var collectionData:ArrayCollection;
private function init():void
{
collectionData = MyArrayCollection
collectionData.filterFunction= filterUrl;
collectionData.refresh();
}
private function filterUrl(item:Object):Boolean
{
return item.Url == data.Url;
}
]]>
</mx:Script>
"MyArrayCollection" has (example)200 arrays with lot of data and some
of them (example, 50 of them) have the same "url" value
(url=www.test.com) . The linearChart has as dataprovider "collectionData".
I want to filter the item renderer (and his linearchart) with this.
The problem is that when i launch the app the tilelist and the
itemrenderer repeat the same linearchart in all the renderers.
I know im close!! Please help!
