[Zope] session and iterating session_data

[Bakhtiar A Hamid]

hi
in an attempt to provide users with list of those online, i'm using sessi=
on to=20
keep track of who's logged in , and who's timed out (inactivity)

in essence,=20
-when users log in, i start a session, and store their username in the se=
ssion=20
object

-i then have an external method that goes thru session data in temp_folde=
r=20
(where session objects are stored) and iterate thru the session objects, =
and=20
return the usernames[1]

this scheme works, but some, maybe many, times, i encountered Key Error[2=
, and=20
many times it's the same key error].

is there anything wrong with my way of approcahing this?  or is there a b=
etter=20
way?

zope2.5.1/zope2.6.0b1, python2.1.3, linux

help appreciated.

tia
