SomaMVC
I've just discovered a new ActionScript MVC framewrok called SomaMVC:

Soma is a Flash MVC Framework (open source) written in AS3 to help you to create your projects by automating common processes, such as loading, structure, pages, assets, and a lot more.

SomaCore
The author started a new Framework, SomaCore which goal is to keep it SIMPLE in terms of usage:

I needed something that will easily allow me to have views and models free of Framework code, without creating tons of files or use any injection. I also wanted a Framework very flexible, so I can use it even for smaller project, being sure I’ll be effective in terms of development time.

SomaUI
Based on SomaMVC, SomaUI is a framework which helps you to create flash based websites/applications.

SomaUI is a AIR-Java tool that is generating sources: the draft of a Flash site based on the Soma framework, ready to use and be taken to a further development. Available for Windows, Mac and Linux.

Thanks Romuland for sharing your code!
