ActionScript 3.0 :: Referencing A Textfield Inside A Movieclip Class From Document Class

Ok, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.

I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().

I hate to be defiant, but what if I don't want to?

Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?

It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.

That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.

HERE ARE THE STEPS I'M TRYING:

- Create new flash document

- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage

- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()

- Set a name for that box using box.name = "test" let's say

- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great

- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";

That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?
