Flex List ItemRenderer with image looses BitmapData when scrolling
- by Dominik
Hi i have a mx:List with a DataProvider. This data Provider is a ArrayCollection if FotoItems
public class FotoItem extends EventDispatcher
{
[Bindable]
public var data:Bitmap;
[Bindable]
public var id:int;
[Bindable]
public var duration:Number;
public function FotoItem(data:Bitmap, id:int, duration:Number, target:IEventDispatcher=null)
{
super(target);
this.data = data;
this.id = id;
this.duration = duration;
}
}
my itemRenderer looks like this:
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" >
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
]]>
</fx:Script>
<s:Label text="index"/>
<mx:Image source="{data.data}" maxHeight="100" maxWidth="100"/>
<s:Label text="Duration: {data.duration}ms"/>
<s:Label text="ID: {data.id}"/>
</mx:VBox>
Now when i am scrolling then all images that leave the screen disappear :(
When i take a look at the arrayCollection every item's BitmapData is null.
Why is this the case?
