Will Professional Adobe Flex 3 be available in some electronic form such as Pdf ?

I have read the read the earlier edition on Professional Flex 2, and thought that was a good book despite some negative comments on amazon.com.

I believe this must be "the book" for Flex 3 developers ... and have been waiting for this book since last year ....

So, I am glad this book is finally out.... unfortunately Flex 4 is just round the corner, and Adobe has released the Flash Builder 4 beta, and I understand there are significant fundamental changes on how things are done with the new version ... sigh ... very soon, we will see books on Flex 4 on the market ...

I have not heard anything from the publisher about it, so I doubt it.

Thank you for saying so. This has been our aim in writing this book: to produce a comprehensive reference for Flex of both breadth and depth, with a balance of both theory and practise.

So are we! A year and a half from beginning to publication, one solid year of writing and editing... whew! :)

I won't dispute your assertion that "very soon, we will see books on Flex 4 on the market," but I no not think this unfortunate. This book took a long time to write for a reason, and that is that it is breaking new ground in being the very first Flex book to be published with so comprehensive a scope.

Since Flex 4 does not posses a feature-complete component set, you'll still be using Halo components for a while. The architecture and other things will change in Flex 4, and there are many improvements in both the Flex SDK and Flash Builder, but some things will not change much, like the profiler, the automation framework, the logging framework, the unit testing framework, how MXML works, how to connect an app with Blaze DS, or how to build an Cairngorm application, to state but a few examples. So a large part of this book will still be current and viable well until Flex 5 comes along in a few years.

And... Flex 4 is still in Beta, at least until the fall (Q4 2009). Few enterprises I have encountered are willing to migrate a codebase to or create a new application on a beta version of a technology, so the timeliness of this book as a reference will be valid as long as there are companies still developing in Flex 3. Having said that, we do plan on updating this book for Flex 4... next year sometime (I cannot say when exactly).

Enjoy your copy of the book! If you have any questions for the authors about the exercises, or you've spotted a possible error, please drop a question on these forums.
