At the bottom of this email.
I'm using nevow from svn, last revision.

I can't understand: why sessions should be "serializzable"? Do you mean
that I should be able to write them to a file whenever I want?

Probably you are right; my app is only made by few test modules. I have
choosed livepage because It is simpler to understand IMHO
Here the code:
from nevow import appserver, loaders, tags as T
from twisted.application import service, strports
from nevow.livepage import glue, LivePage
from nevow import livepage
docFactory = loaders.stan(
def render_choice(self, ctx, data):
def chosen(ctx, choseWhat):
return livepage.set("choosable", \
["Thanks for choosing ", choseWhat])
chooser = livepage.IClientHandle(ctx).transient(chosen)
return T.span(id="choosable")["Choose one:",
site = appserver.NevowSite(LiveExample())
application = service.Application("site")
