(reposting this from the AS3 page, sorry if you're seeing twice, but this topic is in limbo )

I develop my AS3 projects in Flex Builder, which has been magic so far... but now I have a need for components.
There are two obvious paths here:
a) Use the Flash 9 component set (sounds like it works, but takes a bunch of hackwork, and its a small set really)
b) Use the Flex framework components. (I'd like to be able to use these, but am having trouble.)

Does anyone have suggestions regarding this choice?


I am currently trying to use the Flex framework, and have gone through a lot of work (and the entire internet) trying to figure it out. From what I've gathered, this is the way to do it:

Create a new FLEX project, with 1 mxml file:
Code:
 <!-- @mxmlc -default-size 400 300 -incremental=false -->
<Main xmlns="*"/>
This file runs my Main.as file (which extends Application):
Code:
package {
	
	import flash.display.*
	import flash.text.*
	import flash.events.*
	
	import mx.core.*;
	import mx.controls.*;
	import mx.events.*
	import mx.skins.halo.*;
	
	public class Main extends Application
	{
		
		public function Main()
		{
			//initialize flex
			super();
			this.layout = "vertical";
			this.setStyle("borderSkin",mx.skins.halo.HaloBorder);
			this.addEventListener(FlexEvent.APPLICATION_COMPLETE, init); 
		}
		
		private function init(eventObj:FlexEvent):void
		{
			trace("init()");
			var clip:Sprite = new Sprite();
			clip.x = 100;
			clip.y = 50;
			clip.graphics.beginFill(0x00aa00, .7);
			clip.graphics.drawRect(0, 0, 300, 200);
			addChild(clip);
		}
		
	}
}
Now I am under the impression that all of the above would work, except I get one error. addChild(clip) is not able to run because it is trying to add a sprite to the stage, and Flex will only accept Flex display objects.

Can anyone advise?
