If you aren’t using an MVC framework like Cairngorm, Model-Glue, Guasax, or PureMVC for your Flex development, you really should think about starting. Our adoption of PureMVC at andCulture has allowed us to structure our ideas around a concrete paradigm and move on to arguing about more important things.

I’ve implemented PureMVC in both Flash and Flex projects and I’ve noticed that #3 of this post really applies. I mean really applies. As a general philosophy, I believe it’s better to start out with as few Mediators as possible, and structure them (or it) around the logical parts of the application or module—not the View Components or even their hierarchy as much. And, when the Mediator starts to become cumbersome, think about refactoring. 

For instance, for a Flash kiosk I just finished, I more-or-less had a Mediator for each VC—not entirely, but I definitely ended up with a disorganized mess of Mediators, which I affectionately refer to now as Mediator Soup. 

One of the biggest issues is state. Often elements that have their own Mediators should actually be a complex VC with a single, intelligent Mediator. Or, if that doesn’t flow architecturally, approach the VC as a separate Module or component, with it’s own MVC, and interface to it via it’s own API.

I’ve noticed that this approach allows me to think of the application in a more logical way, and seems to keep the code cleaner. I’d appreciate any thoughts or feedback on this.
