Jun Heider just pointed me to the Swiz Framework.
Swiz is a framework for Adobe Flex that aims to bring complete simplicity to RIA development. Swiz provides Inversion of Control, event handing, and simple life cycle for asynchronous remote methods. In contrast to other major frameworks for Flex, Swiz imposes no JEE patterns on your code, no repetitive folder layouts, and no boilerplate code on your development.
Looks very interesting! I’m right in the middle of a quick project that we are using Mate for, so I guess I’ll have to check out the Swiz framework next. Hopefully I’ll have the time to write out some of my thoughts on both frameworks as I finish playing with them.
