http://snippets.dzone.com/posts/show/277#related problem ===> When I create a new coupon first time, it is stored in DB. After saving I try to clear out(delete old session in which coupon object is stored) session using session.delete('partial_coupon') But session is not get clear and also coupon object is not get store in DB.
