i have two classes wich i should load to stage, both works fine when linked to a mc and dragged from library but when i try to added to stage using as i get “TypeError: Error #2007: Parameter child must be non-null.”
any idea??
here is the code of the class that “works” when inserted:

any help is welcome.
this line is the cause:
stage.addEventListener(Event.ENTER_FRAME, frameNumberText);
now my next question is how can i solve this? tried using this but didn’t work either.
solved this predicament changing “stage” for “this”
