title: LightSwitch Open another screen when adding a new 'User'
body: <p>I have been working with VS LightSwith for a couple of days, and I have this question: If I have a DB table of 'Users' in witch I can add or edit an user trough a LightSwitch screen, and that table is connected to another for 'Roles' in witch each user can have 0 or n roles, it is possible to open the Roles screen for that user only when a new user is added but not when is edited? The User table has an Id that is foreign key for the Roles one. </p>
