As most knew, it shuold be taken into account at Controller - Command in pureMVC architecture. But it seems, also I saw in some demos, that simple logic such as validating user input is processed in Mediator. Since Mediator is the manager of Views, I don't understand the role mediator acts. Of course it's clear to do simple check in Mediator, but View&Controller aren't separated clearly, right?
Would anybody offer me some help? Thanks!
