As I'm curious I have a technical question: What's the difference if I read the necessary data in the flow or some milliseconds latter in the view layer? What do I gain?
You gain a cleaner separation of concerns. I simply don't like accessing my persistence layer from the view. The view is passed a model that consisits of Javascript objects, Java beans or DOMs and it should not care where it comes from.
Just IMHO,
