Annoying nulls

1

I’m working on large project and keep getting errors:

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
TypeError: Error #2007: Parameter child must be non-null.

It can be quite frustrating (:

I’ve added two simple overrides to my base classes:


**[SIZE=2][COLOR=#0033ff][SIZE=2][COLOR=#0033ff]public [/COLOR][/SIZE][/COLOR][/SIZE]****[SIZE=2][COLOR=#0033ff][SIZE=2][COLOR=#0033ff]override [/COLOR][/SIZE][/COLOR][/SIZE]****[SIZE=2][COLOR=#339966][SIZE=2][COLOR=#339966]function[/COLOR][/SIZE][/COLOR][/SIZE]**[SIZE=2] addChild(child:DisplayObject):DisplayObject {[/SIZE]
