Title:
  child_of for id field bug report

Status in OpenERP Server:
  Invalid

Bug description:
  For special application I have added parent_id field in user object:

  class users(osv.osv):
      _inherit = 'res.users'
      _description = "Users"
      _columns = {
          'parent_id': fields.many2one('res.users', 'Parent User'),
          'child_ids': fields.one2many('res.users', 'parent_id', string='Children Users'),
      }

  When I make some hierarchy of users I want to add domain or
  permissions for that users.

  Then I try to use domain in action (in xml view definition):
  [('id','child_of',uid)]

  or I try to define record rule for users object:
  [('id','child_of',user.id)]

  and I get always bug report:

  I think it should work for id field as for any other fields.
