This is corrected in release # 95, soon in apps.openerp.com

You have to add a standard account for Fuel Log for the company

This is a GTK Client error only, as https://answers.launchpad.net/openobject-server/+question/201487

Tank you oldbay for the heads up on the GTK-client problem.

I have added a new bug report for this. https://bugs.launchpad.net/openerp-vertel/+bug/1053230

You also added a nice tip for the solution. It seems if I change the behaivor of onchange this bug could be solved. Do you now any example of code that demonstrates this solution?:
"""
Using "onchange( parameter or False )" constructs, you can prevent this.

Editinng rpc.py file in GTK Client (add "allow_none=True" to all xmlrpclib.ServerProxy calls in rpc.py), the problem is not fixed.

Problem is fixed edit wsgi/core.py file in openerp-server (edit all "xmlrpclib.dumps(fault, allow_none=False, encoding=None)" to "xmlrpclib.dumps(fault, allow_none=True, encoding=None)" ), so works.
I do not know - whether it is correct.
