Where must be custom logic in pureMVC (as3)? - actionscript-3

Question

I tried to write small as3 program based on framework pureMVC.
I understood basic principles of it, but I can't understand, where I must place custom logic.
For example, I must load 10 images. I created command, that init Proxy.
package app.controller
{
import app.model.GalleryProxy;
import dicts.Constants;
import org.puremvc.interfaces.INotification;
public class LoadFilesCommand extends BaseCommand
{
public function LoadFilesCommand() { }
override public function execute(note:INotification):void
{
facade.registerProxy(new GalleryProxy(Constants.FILES_LIST));
}
}
}
And Proxy is:
package app.model
{
import dicts.Constants;
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.Loader;
import flash.display.LoaderInfo;
import flash.events.ErrorEvent;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.net.URLRequest;
import org.puremvc.interfaces.IProxy;
import org.puremvc.patterns.proxy.Proxy;
public class GalleryProxy extends Proxy implements IProxy
{
public function GalleryProxy(list:Vector.<String>)
{
super(Constants.PROXY_GALLERY);
_fileList = list;
_total = _fileList.length;
load();
}
public function get currentImage():Bitmap
{
return _images[_index];
}
//--------------------------------------------------------------------------
// PRIVATE SECTION
//--------------------------------------------------------------------------
private var _fileList:Vector.<String>;
private var _total:uint;
private var _loaded:uint = 0;
private var _images:Array = [];
private var _index:int;
private function load():void
{
var loader:Loader;
for (var i:int = 0; i < _total; i++)
{
loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoadHandler);
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
loader.load(new URLRequest(_fileList[i]));
}
}
private function imageLoadHandler(event:Event):void
{
var info:LoaderInfo = LoaderInfo(event.currentTarget);
_images[Constants.FILES_LIST.indexOf(info.url)] = info.content;
info.removeEventListener(Event.COMPLETE, imageLoadHandler);
info.removeEventListener(IOErrorEvent.IO_ERROR, errorHandler);
_loaded++;
if (_loaded >= _total)
sendNotification(Constants.COMMAND_SHOW_MAIN);
}
private function errorHandler(event:ErrorEvent):void
{
throw new Error("bad link or internet disconnect");
}
}
}
Now my Proxy is loading images independently (functions load() and imageLoadHandler)
Is it correct?
Or I must move this logic to Command class?
Or I must create some LoadService.as, which will contains this logic?
What is the correct variant for pureMVC?

Do you want to load your 10 images on application startup? If not, make load() public and call it from a Mediator, responding to a UI event.
If so, what you have will work fine. One alternative would be writing GalleryProxy so it doesn't call load() in the constructor - instead, you could have the Command register the proxy, load the image list, and call proxy.load(images[i]) in a loop.
