I have CVS ZEO2, Zope 2.5.1 running on WinXP, PythonWin for Python 2.1 installed. I need to learn how to use a debugger to get information on what's happening on live objects (i.e when a form is submitted, I'd like to view the request and step through) Specifically I have a strange string.strip() error that just popped up on a customized Formulator product I'm working on, and I figure I should be able to debug this better than the traceback (see below). I can open up PythonWin or zope's console python and after Import Zope'ing, I can access the object model. While that's been invaluable as a sort of offline code-completion, that really isn't helping me debug live object behavior, which is where I'm running into some diffuculty as my product comes into shape. I'd really like to learn how to do this with the console or PythonWin, rather than use WingIDE or another IDE, but whatever it takes I'll do. With the setup I have, is there anything I can do to debug what happens at a specific request like the one described here? Zope has encountered an error while publishing this resource.
