Right. I fixed that in the example code in subversion.

Yeah, you can't use the standard one. I now removed <html> and <body>
from the standard edit template and made the add form use that instead.
So if you check the example application again it should work.

grok.template(...) doesn't seem to work on grok.AddForm, so you have to
specify template as a class variable instead. I don't know if there's  
a reason
for it not to work.
