[Zope] publish() hook

[Stadtverwaltung Schwarzenberg]

Hi there!

I'd like to add a little functionality to my ZPublisher.Publish.publish
method. So I created a new Product and in the __init__.py file of ths
product I put code like this:

import ZPublisher

def publish_new(same fingerprint as ZPublisher.Publish.publish):
    response = ZPublisher.Publish.publish_old(paramaters)
    #
    #aditional functionality
    #
    return respone

ZPublisher.Publish.publish_old = ZPublisher.Publish.publish
ZPublisher.Publish.publish = publish_new

Using this code Zope starts up w/o error but I don't see any effects of my
new publish method. In fact - even if there is an error in my additional
code it never raises an exception so I figure that my new pubish method
never gets called.

Some additional info: I'm running Zope 2.4.1 on a WinNT machine.

Can anyone help me out? Please?

Thanks
Falk
