Should have the ability to make jsf backing beans with roo jsf addon with usage like so:
web jsf backingBean RegistrationBackingBean --addManagedBeans AManagedBean, BManagedBean, CManagedBean, UserManagedBean etc. to inject managedBeans to backingBeans.
You really don't need them ManagedBeans if you use the generated java beans, but roo jsf addon seems to make it already. Now we need to inject the ManagedBeans to relevant BackingBeans. There is something fundamentally odd with the current concept of asking users to use just the RooJsfManagedBean as both the ManagedBean and the BackingBean. They are entirely diff concepts in the JSF world.
