Thank you, Russ.
I notice that It is exaggerated to change View.dispatch method.
My proposal can be implemented by inheriting View.
With reference to your opinion, I wrote this PredicateProcessView:
https://gist.github.com/4440994
Inheritin this View, We can benefit as well as my proposal.
This discussion was informative for me.
Thank you.
