NullPointException when setting value from Converter

I have an application where I need to calculate data coming from a particular relationship.

When usuarioController.view == 3 , Login is set to Usuario and Plano (already persisted) to Login so that in the next step UsuarioController calculate the sum of the price of all plans contained in all logins, however the Login is not populated with Plano . Is this a problem in Converter?
