Hi,
When I'm creating new warehouse, getting an error
File "/home/apagen/workspace/odoo/openerp/models.py", line 4191, in _create
cr.execute('update '+self._table+' set parent_left=%s,parent_right=%s where id=%s', (pleft+1, pleft+2, id_new))
TypeError: unsupported operand type(s) for +: 'NoneType' and 'int'
I need help asap.
