I would say that the FirstClass doesn't exists at RUNtime... If the
SubFirstClass is declared in your main SWF and FirstClass in an external
SWF, the inheritance is executed before the exeternal SWF is loaded.
If you could create the subclass after the SWF is loaded, this should
probably work... but it's not quite easy to do with only AS2.
The intrinsic classes (or exclude.xml) only allow you to compile with a
class which is not implemented, but will be at runtime...
You must never forget that declaring a class is only creating a variable
of Function type... Your code is nearly equal to
SubFirstClass.prototype = new FirstClass();
If FirstClass doesn't exists when you execute this code, it won't works,
and it's normal! ;o)
That's why when classes are declared in external SWF, and we want to use
an intrinsic declaration to use it in a main SWF, it's better to use
composition, because we have control over instanciation, but not over
declaration...
