If the data is captured in the backing bean, I see no reason you can't pass that information to some business classes. With that being said, I don't think having a minimal amount of business logic, so long as it pertains to building the view correctly, in the backing bean is a problem. It helps though to think of the backing bean as the controller in the MVC
pattern. So it should more or less direct traffic and hand off business logic to helper classes when possible. My opinion anyway.
