[mod_python] KeyError Exception when doing sys.modules[class.__module__] (vampire?)

Hi,

Thank you very much for the fast response. I was trying to get a
reference to the object based on name, as I found in the Dive Into
Python tutorial:
http://www.diveintopython.org/file_handling/more_on_modules.html.

It seems that using globals() will also a give similar result. I think
that will work too. Thank you very much! I appreciate it.

Best regards,
Keerati Inochanon
