Hi Again Amy,
Realizing that wasn't right I am now just getting a blank screen .. I am still
working on it so I'll keep you posted.
package samples.photoviewer
{
import flash.events.*;
import mx.collections.ArrayCollection;
import mx.collections.IViewCursor;
import mx.events.CollectionEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.http.HTTPService;
import mx.utils.ArrayUtil;
public class PhotoService
{
private var service:HTTPService;
public var app:PhotoViewer;
[Bindable]
public var galleries:ArrayCollection;
public function PhotoService(url:String)
{
service = new HTTPService();
service.url = url;
service.addEventListener(ResultEvent.RESULT,
resultHandler);
service.send();
galleries = new ArrayCollection([]);
galleries.addEventListener(CollectionEvent.COLLECTION_CHANGE, changePolicy);
}
private function resultHandler(event:ResultEvent):void
{
var result:ArrayCollection = event.result.galleries.gallery
is ArrayCollection
? event.result.galleries.gallery as ArrayCollection
: new
ArrayCollection(ArrayUtil.toArray(event.result.galleries.gallery));
var temp:ArrayCollection = new ArrayCollection();
var cursor:IViewCursor = result.createCursor();
while (!cursor.afterLast)
{
temp.addItem(new Gallery(cursor.current));
cursor.moveNext();
}
galleries = temp;
}
private function changePolicy():void {
app = new PhotoViewer();
app.views.createComponentsFromDescriptors();
}
}
}
