Thanks for the reply.
Also, it seems like a very bad idea to have 2 classes share
a name. I thought one goal of using swfs to contain classes was to make
upgrades easy?
I understand your quandry with legacy code, but I don't
believe trying to overwrite an existing class makes sense. Can't you use
'extends' to add your new method?

Hi Jim,
The classes are stored in _global. So in
theory you can manually override the class (not tested yet)
class com.mycompany.MyClassV2 {
...
}
// code on the _root of movieB.swf
_global.com.mycompany.MyClass =
com.mycompany.MyClassV2;

Subject: Re: [osflash] Using swf to
import external classes
Thanks for your recommendations. The problem is that this is a
complex environment with multiple teams of developers from multiple companies
attempting (in theory at this point) to use the same codebase. Might not
even be possible...
Regarding your comment "There's no simple way to have two classes with
exactly the same name"
Is there any way at all? I can only think of hideous hacks...

Name your classes
differently, or use a different package name.
There's no simple way to
have two classes with exactly the same name.
You could name your classes
like:
com.company.v1.MyClass
com.company.v2.MyClass
Or, if you
really don't want to recompile, have your loader load
movieB.swf first.
Or if that's not an option, create a swf that only
contains the new
MyClass, than have it load:
1. newMyClass.swf
2. movieA.swf
3.
movieB.swf
