Problem with a value assigned in a session mysteriously being overwritten by 0
Hi, I'm currently using Zope 2.5.1 and have recently discovered a really nasty problem which I cannot explain and am having great difficulty finding a workaround. I have a log-in process with several forms and I use a session object to keep some data (ie. foreign keys) between forms. This has so far worked very well but now one of the values is being overwritten by 0. I can tell when this is happening but can't work out why. Brief description of what's happening: 1st form -> PythonScript: generate 'id_person' do some database work, assign session['id_person'] = id_person, assign session['username'] = username -> call 2nd form via request.response.redirect 2nd form -> PythonScript: do some more work dependent on the key 'id_person' Observations: The 'id_person' is still visible in the session object in the 2nd form but has been assigned to 0 by the PythonScript. But it is the only session variable which has been overwritten. I can't think how this would affect things but I have changed some calls from context.Objectname(request, context) to request.response('Objectname'). Any ideas? The only current workaround I can think of is to pass the key as a hidden value through the form but I'd like to avoid that if possible. Charlie
the sessioning stuff has seen many improvements and fixes since 2.5.1. upgrading your zope might help. jens On Wednesday, Nov 13, 2002, at 08:40 US/Eastern, Charlie Clark wrote:
