Note, please, that you are allowed to call this method only,
when you return to the dispatcher after you have made a "dispatch out"
(i.e. "__call__").

This is very similar to Zope's ":method".

The "xxx__disp" is either the name of a button (more precisely,
input type=submit) or a hidden variable, then usually in the
form "__disp" with the value specifying the destination.

With the "__disp", you specify the destination page that should
be rendered when the variables are saved.

Mostly (see the "update" remark above).

Maybe a bug or an incompatibility with your session product?

You know, how you should report errors?

  Error Type, Error Value and traceback are necessary information
  to say anything about a problem.


I will be away for several weeks and thanks to lots of email ads,
my mailbox will probably run out of quota. Thus, be patient
and submit the additional information in about 3 to 4 weeks.
