Cairngorm and Flex

I am planning to use Cairngorm library with Flex builder. On Adobe page for Cairngorm, you can also download, Eclipse plugin for Cairngorm.

The good thing about Cairngorm is that, it (almost) forces you to have a specific directory structure for you Flex application.

You must type tons of extra code, to make a Cairngorm application to work, but it helps you separate Model/Data from View/UI. It is based on Commands and created events. So almost everything necessary is abstracted from each other.

You also must have a big enough project on Flex that requires Cairngorm framework. If you Flex application is simple, don't use it. If your application needs extending, developed with more than one developer or needs continuous modification, Cairngorm is definitely the way to go. So Cairngorm is good for medium to enterprise level applications for Flex.
