This is one of those "if it doesn't work, don't do it" cases. Don't use external methods. They're an anachronism left over from when it was more difficult to integrate Python with Zope.
Instead, use a browser view. If you use ZopeSkel to create the basic skeleton package, it's really just as easy as doing an external method, and will cause you a lot less trouble.
