[Zope] - BoboPOS problems

[Pavlos Christoforou]

Hello Zopistas

I created an extension (a hit counter) that includes the class
definition in the same source file as the method. After a couple of days
ZopeHTTPServer crashed without any apparent reason. On restarting I got
the following errors in the server.log file:

Traceback (innermost last):
  File "serve.py", line 99, in ?

SystemError: Failed to import class Counter from module __main__


As I understand the problem has to do with pickle not finding the class
definition. I assume that the External methods object uses exec to load
and store only the function definition into Zope/BoboPOS and not any other
code that finds in the source file. 

I hacked Main.py and included a 
from Counter import Counter 

but it did not work. So now I am stuck without Zope :-(
Also the change was made 2 days ago and all objects from there on include
refrences to the counter object.

Am I missing something simple or have I messed things up badly?
