My application is modelled after NerdDinner presented in http://www.asp.net/mvc/learn/. I am having problem saving my posted edit and create pages even none of the business rules in the following Helper class is violated. The only place that I can think of is the database table foreign keys are violated. Could someone help me to catch the database exception? Thanks.
