At least I think it's an error (either in my understanding or in the book). First off, I think the books great. Finally something that's trying to explain what's going on. Zope looks so cool, but it's been hard for a hardcode PHP and Perl programmer like me to get my brain around it. Anyway, my suggestion is that all the image URLs be fixed so that your book can be easily mirrored with normal web-tools. Perhaps even offer a version that's downloadable. When I went to mirror it, my mirror software choked on image urls like: http://www.zope.org/Members/michel/ZB/SimpleExamples.html/Figures/5-7.png The mirror was so I can use it at home where I don't have a reasonable net access (very flaky 56k, it hoses up frequently as it's through work). The error or problem that I have run into is that I can't get the Guest Book in chapter 5 to work. They python method listed there does not work for me. I'm using Debian Unstable (Woody) with these versions of packages: ii zope 2.2.2-3 The Z Object Publishing Environment ii zope-bytecodeh 0.1.7-2 Rewrite bytecode of functions to do unlikely ii zope-pythonmet 0.1.7-2 Allows ZopeMethods to be written in plain Py That's bytecodehacks and pythonmethods on the bottom there. The error message is: Error Type: NameError Error Value: context I have no idea how to fix this, so I'm asking here.
