I'm using a third party library, one of their classes tries to extend ArrayCollection like:
public class Garage extends ArrayCollection
I get a compile error about that though like:
The definition of base class ArrayCollection was not found.
I don't understand what that means - flash can't find the definition of ArrayCollection? In my main as3 file (the one associated with the movie) I can import and use ArrayCollection with the same statements. What am I missing?
