Re: [flexcoders] mx:states vs mx:viewstack when and which?

Wed, 03 May 2006 12:48:07 -0700

I'm pretty keen on wrapping all view changes in a state. Even if you use a viewstack, as Matt said, you can have a state which sets that selectedIndex. The nice thing about doing that is you have a simple abstraction, which lets you ditch the viewstack at a later date, and just change your state code. It also gives you one place to handler transitions, instead of having to specify show/hideEffect for you viewstack views, which makes things a lot more consistent and easier to follow.
