Technical Notes

As Flex continues to grow as the choice RIA technology, many developers start investigating and apply JEE patterns to Flex implementations. Cairngorm is a Model-View-Controller framework - endorsed by Adobe - that is widely popular within the community. Cairngorm, however, is not ready for 100% "out-of-the-box" implementations of production applications.  The current versions of Caingorm (version 2.2 or before) need to be "tweaked" for production use.
