I have been hammering at this for some time now, and it is getting a little frustrating.
1. I have a document class that adds a TextField.
2. The Doc class then adds another custom class (MovieClip).
3. Inside that custom class (MovieClip) is a button with an addEventListener that needs to update the TextField on the main stage (or root).
I have tried so many possible solutions that I am not going to list them here, I am sure I must be doing something fundamentally wrong...
