I have the same problem, with the released version 6.0.1 on Ubuntu 10.10. The error trace is

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: HTTP 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 88, in default return request.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/addons/openerp/controllers/utils.py", line 112, in wrapper return fn(*args, **kw) 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/addons/openerp/controllers/execute.py", line 21, in index return actions.execute(action, **data) File "/home/dwa/openerp-6/web/addons/openerp/controllers/actions.py", line 380, in execute return action_executor(action, data) File "/home/dwa/openerp-6/web/addons/openerp/controllers/actions.py", line 268, in act_window display_menu_tip=display_menu_tip) File "/home/dwa/openerp-6/web/addons/openerp/controllers/actions.py", line 85, in execute_window return Form().create(params) File "/home/dwa/openerp-6/web/addons/openerp/controllers/utils.py", line 112, in wrapper return fn(*args, **kw) 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/addons/openerp/controllers/form.py", line 195, in create form = self.create_form(params, tg_errors) File "/home/dwa/openerp-6/web/addons/openerp/controllers/form.py", line 186, in create_form 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. _______________________________________________ Mailing list: https://launchpad.net/~openerp-dev-web Post to : [email protected] Unsubscribe : https://launchpad.net/~openerp-dev-web More help : https://help.launchpad.net/ListHelp
