unable to login to OpenERP7

Question

I am stuck in really weird problem, and i am unable to figure out the cause of the problem. i have OpenERP installed on my development environment and production environment, both on Ubuntu. On Dev site all is working fine. Earlier yesterday, on production it was working ok. but all of a sudden i started getting error:

AttributeError: 'NoneType' object has no attribute 'create'

here is the full trace of the error from pop up:

    AttributeError: 'NoneType' object has no attribute 'create'

after i close popup i am still on my openERP login form.

I am not sure what actually has happened. All i was trying to change my modules UI using view.xml. I used this xml file to recreate this issue on my dev server, but on my dev server it is working perfectly. Plz let me know if this is because of permission issue(though i cant remember messing around with permissions).

Plz let me know what i am doing wrong. If any furthur info is needed, feel free to ask for that. Thanks

You have a problem on an Action Rule. Try deactivating them to see if you can login.

Open psql or a pgAdmin Query window, and run:

update base_action_rule set active = 'f'

Then later on go to Configuration -> Technical -> Automated Actions, and make an Advanced Filter: Active is False, so you can see them and try to find the cause for the problem.

A more drastic solution is to temporarily rename the base_action_rule directory in the addons directory and restart the server. You will get a warning because the module won't be loaded, but the server will start.
