Re: [flexcoders] JSON as dataprovider
Ok I've actually had to do this slightly different - as there will be
a lot of flipping between items; what I'd hoped to do was something
like like a static var of 'db' as ArrayCollection and do a
db.removeAll() -- but when I've even manually parsed the var arr and
tried doing a db.addItem(arr[x]) it's not working...

What exactly are you trying to achieve? You have to be clearer on what you are after so that we can help you. Fidel.
[flexcoders] JSON as dataprovider
I've got a class that gets a JSON object - and within this JSON object is a list of items. I'm trying to do what I think is very simple -- but I'm missing something -- being able to bind a tilelist to an array of this returned objects.items. I've tried manually parsing through these items and doing an addItem(return.items[i]) into an arraycollection - but this doesn't seem to be working at all. Any thoughts or examples please?

Get the as3corelib (http://code.google.com/p/as3corelib/) and do the
following:
import com.adobe.serialization.json.JSON;
// get the results as JSON
var results:String = String(httpService.lastResult);
// decode them into an object
var obj:Object = JSON.decode(results);
// get the bindings as an array
var test:Array = obj.results.bindings as Array;
// create a collection that can be used by the data grid
var arrayColl:ArrayCollection = new ArrayCollection(test);
All the best,
Fidel.
Sorry, let me correct that:
import mx.collections.ArrayCollection;
import mx.rpc.events.ResultEvent;
import com.adobe.serialization.json.JSON;
private function onJSONLoad(event:ResultEvent):void
{
var rawData:String = String(event.result);
var arr:Array = (JSON.decode(rawData) as Array);
var dp:ArrayCollection = new
ArrayCollection(arr);
grid.dataProvider = dp;
}
You can find the example in the samples directory. The code I posted
previously is somethin I used in another test.
All the best,
Fidel.
