Basically I am using data binding to show/hide,
enabled/disable different components on my view where I need to. Also
in Flex2 the view states are really nice as well, but you have to be careful of
a few caveats (still in the middle of figuring out some
details).

What are you using instead of ViewLocators to handle view specific
logic. I know that Jesse Warden swears-by still using a common
ViewLocator (a good topic for debate), but what does the committee
recommend as best practice?
