Problem while creating a new reservation

[LF2T]

Hello guys,
Every time I try to create a new reservation it gives this error :

File "C:\Users\Ismail\workspace\odoo-8.0-20160916\openerp\addons\hotel_reservation\models\hotel_reservation.py", line 321, in set_to_draft_reservation
self.delete_workflow(cr, uid, [reservation.id])
ValueError: "global name 'cr' is not defined" while evaluating
u'set_to_draft_reservation()'

even when i try to update the module with demo data it gives :

ValueError: "global name 'cr' is not defined" while evaluating

Thnx
