[Grok-dev] Integrating session logins into Kirbi

[Luciano Ramalho]

After I found the precious NudgeNudge example I started to integrate
users and logins into Kirbi.

Currently my problem is that whenever a navigate to the Kirbi index
page without having previously authenticated, I get a system error
with the traceback reproduced below.

I suppose the session machinery is not properly setup, but I believe I
did everything that NudgeNudge does to setup the PAU from Python code
(module app.py) [1]. Perhaps something is missing from the zcml, but I
am having a hard time checking this because NudgeNudge is quite old in
Grok time, so the layout of the project is very different, and so are
the .zcml files.

[1] http://svn.zope.org/Sandbox/luciano/kirbi/src/kirbi/app.py?rev=78892&view=log

Any ideas where I should look?

Regards,

Luciano
