[Flashcoders] AS3 JSON.decode() not working :(

Ali Drongo Tue, 03 Jun 2008 06:58:27 -0700

Hiya, I can't seem to get the JSON.decode() method to work. I haveread a couple of blog tutorials and the string is tracing fine butwhen I pass it I get the message:


Error: Unexpected j encountered
        at com.adobe.serialization.json::JSONTokenizer/parseError()
        at com.adobe.serialization.json::JSONTokenizer/getNextToken()
        at com.adobe.serialization.json::JSONDecoder/nextToken()
        at com.adobe.serialization.json::JSONDecoder()
        at com.adobe.serialization.json::JSON$/decode()
        at JSONExample/decodeJSON()
        at flash.events::EventDispatcher/dispatchEventFunction()
        at flash.events::EventDispatcher/dispatchEvent()
        at flash.net::URLLoader/onComplete()

I'm not sure what I'm doing wrong, if someone could point me in theright direction it would be a big help.

Cheers!
Ali

my code:

                private function createLoader():void
                {
                        trace("createLoader");

var request:URLRequest = new URLRequest("http://www.flickr.com/services/feeds/photos_public.gne?tags=flex&format=json");

                        loader = new URLLoader();
                        loader.load(request);
                        loader.addEventListener(Event.COMPLETE, decodeJSON)
                }               
                private function decodeJSON(event:Event):void
                {
                        trace("event target:"+event.target.data);
                        var my_ar:Array = JSON.decode(event.target.data) ;
                }

ps I'm also getting these error msgs when I compile:
