10. NEW NAME PROPOSAL
ZAMF!

11. CAIRNGORM

12. CAIRNGORM CLARIFICATION
Can seem complicated at first
DOES NOT HAVE TO BE HARD
Oen not well presented for new users.
Not only for large projects
Not only for LiveCycle Data Services
Don’t try to compare to server side MVC (Ruby on Rails,
CakePHP, etc)

13. CAIRNGORM
A lightweight, prescriptive framework for some of the
challenges consistent with the Flex RIAs we have
encountered
Using a small number of relevant design patterns, where the
moving whole is slightly greater than the sum of its static
parts
A microarchitecture for RIA development—a starting
point for your technical architecture that solves the
problems as they have been solved successfully before

14. CAIRNGORM
IN 15 MIN
Trust Me. You Can Do It!
Don’t Take Notes
Hold Questions

19. CAIRNGORM
COMMANDMENTS
Never change model data from the view.
I don’t care if you can
Use Cairngorm Events for application wide events
Use Naming Conventions
LoginEvent, LoginCommand, LoginDelegate, LoginResponder, LoginVO
Use Reverse DNS Folder Structure
Charge More for Cairngrom Work
