This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I have covered Flex framework including MXML and ActionScript in this book in chapter 1, 2 and 3. Cairngorm, PureMVC, Mate are application frameworks and these are not covered in this book. Currently I have no plan but will definitely write book on advance Flex and will include these frameworks in that.
