I must have stumbled into the Flash API at the right time as I'm
trying to use the new TileLayerOverlay functionality with a custom set
of tiles I made using Arc2Earth and stored on Amazon S3.
I'm having problems trapping the error when my a particular tile (png)
is requested but does not exist. (The tiles that do exist get loaded
correctly.) I've tried lots of combinations of try:catch blocks and
event listeners but I still can't trap loader errors.
I always get the
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
error, for each tile call.
For Amazon S3 if you make a url request to a file that doesn't exist
you get back an xml response. I tried moving my tiles to linux server
that would report a 404 error, but that didn't help. I also tried
adding a surogate DisplayObject and returning it on load errors, to no
success. I also thought about writing a tile reflector page in php/
python/asp that would return tiles if they exist, but what to return
if they don't exist?
Below is an excerpt from my class implementation of TileLayerBase. Am
I missing something?
Thanks in advance for any suggestions.

public override function loadTile(tilePos:Point,
zoom:Number):DisplayObject {
var loader:Loader = new Loader();
var tileUrl:String = "http://s3.amazonaws.com/mybucket/subfolder/";
+ zoom + "/" + tilePos.x + "/" + tilePos.y + ".png";
configureListeners(loader);
var request:URLRequest = new URLRequest(tileUrl);
try {
loader.load(request);
} catch (error:Error) {
trace( "Failed:", error );
}
return loader;
}
private function ioErrorHandler(event:IOErrorEvent):void {
trace("ioErrorHandler: " + event);
}
private function
configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(IOErrorEvent.IO_ERROR,
ioErrorHandler);
}
