a:5:{s:4:"type";s:12:"BuildingInfo";i:0;a:9:{s:2:"id";s:1:"1";s:4:"isim";s:7:"Silahci";s:6:"userid";s:2:"29";s:1:"x";s:3:"200";s:1:"y";s:3:"236";s:5:"depth";s:1:"1";s:5:"level";s:1:"4";s:7:"rebuilt";s:1:"0";s:9:"dateAdded";s:4:"null";}i:1;a:9:{s:2:"id";s:1:"2";s:4:"isim";s:8:"Kahraman";s:6:"userid";s:2:"29";s:1:"x";s:3:"200";s:1:"y";s:3:"336";s:5:"depth";s:1:"2";s:5:"level";s:1:"2";s:7:"rebuilt";s:1:"0";s:9:"dateAdded";s:4:"null";}i:2;a:9:{s:2:"id";s:1:"3";s:4:"isim";s:8:"Belediye";s:6:"userid";s:2:"29";s:1:"x";s:3:"300";s:1:"y";s:3:"450";s:5:"depth";s:1:"2";s:5:"level";s:1:"2";s:7:"rebuilt";s:1:"0";s:9:"dateAdded";s:4:"null";}i:3;a:9:{s:2:"id";s:1:"4";s:4:"isim";s:8:"Askeriye";s:6:"userid";s:2:"29";s:1:"x";s:3:"400";s:1:"y";s:3:"550";s:5:"depth";s:1:"2";s:5:"level";s:1:"2";s:7:"rebuilt";s:1:"0";s:9:"dateAdded";s:4:"null";}}

this is a gonna be a flash game i was planning on building a preloader over whats received as bytesLoaded and bytesTotal
like

        private function _onData(event:ProgressEvent):void {
            
        /*var dataholder:dataHolder = new dataHolder();
        var sonuc = dataholder.putData(event.data);
            for(var o in sonuc)
            {
            addChild(sonuc[o]);
            trace(sonuc[o].isim);
            statusText.appendText(sonuc[o].isim+"
");
            }*/
             trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal);
             trace(event.toString());
            readResponse();
        }

does anybody know why do i get 0 for bytesTotal ???
