Loading Dynamic Image from Library

Question

In a Flash (Actionscript 3.0) project I'm working on, I'm trying to load a PNG file from the library, however which icon should load is not established until run-time.

The project is a weather bar that loads an icon associated to the data feed that's returned as a JSON object. I have tried the following:

var iconData:Class = getDefinitionByName("i"+image);
var i:* = new iconData(130, 130);
var bitmap:Bitmap = new Bitmap(i);
if(p==0){
    today_mc.today_icon.addChild(bitmap);
}

There is a bunch of evaluation that happens to determine "image".

All of the imported files are included as Classes for use in Actionscript, as seen here:

icon as classes

The error I'm getting is:

Implicit coercion of a value with static type Object to a possibly unrelated type Class.

So if the JSON response says the weather code is '33', and I determine in the script that code 33 = icon 4 (i4), I need to load i4.png to the stage.

In the example I read on the Adobe Site for the function getDefinitionByName, located here, they use the as operator to evaluate the expression before assigning the value to a variable.

So I would recommend trying this first:

var iconData:Class = getDefinitionByName("i"+image); as Class;

Also be sure that you have the proper import statements specified. In the linked example, they list the following; however, the first two I'm unsure if you need based on your application's needs:

import flash.display.DisplayObject;
import flash.display.Sprite;
import flash.utils.getDefinitionByName;
