[Launchpad Bug Tracker <711190@xxxxxxxxxxxxxxxxxx>]

Devishree Brahmbhatt (OpenERP) (dbr-openerp) has assigned this bug to you for OpenERP Web Client:

Hello,

We have run into this issue when deploying the OpenERP web client behind
Apache, where requests from clients are not necessarily served by the
same process every time.  However, this error can be reproduced using
the shipped OpenERP development client.  I give these steps below, but
simply suggesting that we don't use the file backend is not a solution.

Steps to reproduce:
 1) Add the following lines to openerp-web.cfg (tools.sessions.storage_path must be an existing directory):
      [/]
      tools.sessions.storage_type = 'file'
      tools.sessions.storage_path = '/var/tmp/sessions'
 2) Start the OpenERP web client development server.
 3) In a browser, navigate to the web interface and log into a database.  Open a list view (Sale Orders, for example).
 4) Kill the server (i.e. Ctrl-C).
 5) Start the server again.
 6) Refresh the page in your browser.

Expected behaviour:
 The current page will simply be re-displayed.

Actual behaviour:
 The following traceback is sent through to the browser:
Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/cherrypy/_cprequest.py", line 606, in respond
    cherrypy.response.body = self.handler()
  File "/usr/lib/pymodules/python2.6/cherrypy/_cpdispatch.py", line 25, in __call__
    return self.callable(*self.args, **self.kwargs)
  File "/home/dwa/openerp-6/web/openobject/tools/_expose.py", line 182, in func_wrapper
    res = func(*args, **kw)
  File "/home/dwa/openerp-6/web/openobject/controllers/_root.py", line 68, in default
    if obj.has_new_modules():
AttributeError: 'NoneType' object has no attribute 'has_new_modules'

Refreshing the page again will cause this error to go away.  However,
the following traceback is then sent through to the browser:

    return tw.form_view.ViewForm(params, name="view_form", action="/openerp/form/save")
AttributeError: 'module' object has no attribute 'form_view'

The traceback is displayed in a purple box in the browser, with the
OpenERP interface in the background.  If the traceback is dismissed,
then the interface is there as normal.  However, clicking on any link
that use a list view (i.e. sidebar menu items or module links which
should display a dashboard) will cause it to reappear.

As far as we have determined, the only way to get rid of it is to clear
the session cookie in the browser, or to delete the session information
on the server.  Neither of these should be necessary.
