Yes, you're missing the rest of the error message. Show the
whole thing, including the stack trace, and I'm sure it'll be
clear that the error happened long before jeez was involved.
I figure that the line in error is
self["name"] = filename
and that what you really need is
self.data ["name"] = filename
You also have a similar problem on the last line of the first class.
