Luke Bayes and Ali Mills of PatternPark made a presentation for the Silicon Valley Flex Users Group (SilvaFUG) of 9 different frameworks and toolkits for creating Flex applications: Cairngorm, PureMVC, ARP, MVCS, Flest, Model-Glue: Flex, ServerBox Foundry, Guasax, and Slide.

Their Conclusion?
“PureMVC by Cliff Hall beats out the alternatives“.

• Composition over inheritence
• Liberal use of Interfaces
• Indirection is used but not overwhelming
• Instance members hide singleton references from application code
• MXML views can be extremely thin
• Benefits of Cairngorm, with few of the disadvantages.

I must admit I never used PureMVC, the only framework I’m currently using is Cairngorm, even if I bookmarked the pureMVC page long time ago promising myself to watch it more in deep. Now it’s time to keep the promise.
