Hi All,
I've also tried posting this on the flex support forums in case anyone
frequents there (although they're being painfully slow at the
moment...)
I have a TileList displaying images loaded from a ByteArray. In MXML
code I have something like
<mx:TileList id="myTileList" dataProvider="{CairngormModel.byteArray}"
itemRenderer="MyItemRenderer" />
MyItemRenderer is just a class that extends mx.controls.Image. The
data setter is overriden, loading the passed ByteArray into a Loader.
The MXML code above works and renders fine, however I'm trying to do
the equivalent in actionscript, which should go something like this:
> public class MyTileList
> {
> private myTileList:TileList = new TileList();
> public function MyTileList()
> {
> myTileList.itemRenderer = new ClassFactory(MyItemRenderer);
>
> BindingUtils.bindProperty(myTileList,"dataProvider",CairngormModel,"byteArray");
> }
> override protected function createChildren():void
> {
> addChild(myTileList);
> }
> }
Yet this doesn't render anything. The debugger indicates the
dataProvider field never changes (is always null). Why isn't the
binding executing?
The alternative approaches I've tried include binding a setter to the
CairngormMode.byteArray, using bindSetter(). This function triggers
when the value changes, so I just set myTileList.dataProvider manually
within the setter. This is followed with a call to
myTileList.invalidateProperties() - still nothing is rendered, even
though the debugger reports the dataProvider as the ByteArray.
Am I missing something simple? Why does the MXML work and not the ActionScript?
Any clues would be much appreciated.
Kind Regards,
Ciarán
