Wanna know what happens next? So do I but this book won't tell you.

Try Adobe's Developer pages. They are much more useful.

This book hasn't been edited at all.
No structure at all. Full of errors.
It seems like the authors forgot to agree on who is gonna cover what.
The third chapter is just rephrasing of the previous chapter.
There is some useful information hidden in the book but it's really a pain to read.
I suspect the authors are designers that have by accident started programming.
And worse: they wrote a book.

Well I have to admit so far I've never been really happy with any book from 'Wrox'. This one does have some good examples, and it has been one of the better books I've had from Wrox. However, I like my Programming Flex 2 from Oreilly better. If you already have a couple books on Flex and are just looking for a bit more information, this one does have some pretty advanced examples in it - and is worth buying (but personally I'd try to save a couple bucks and buy it used).

I've always been a big fan of the Wrox series, but I was rather disappointed with this book:

* I found the learning curve was too erratic. I have a background in Actionscript so I wasn't phased when they showed lots of code in the early chapters, but it would certainly scare others away. At other times it went into tedious detail about something that was really obvious...

* The tone of the book is dry and dull. I'm normally someone who reads books from cover to cover, but I'll admit I started skimming through a lot of the material.

* The book covers a lot of topics, but in relatively little depth.

* Commits the cardinal sin of having non-compilable code.

* The chapter on Flex Data Services was just criminal - it only talked about *configuring* the server, not actually *using it*!

* At no point do you ever BUILD A PROPER FLEX DATA-DRIVEN APPLICATION!!!

Having said all that, the book does make quite a good reference book as it touches on virtually ever part of the Flex ecosystem.

I thought this book would teach you how to code but in the end almost all of it is just code snippets that you really can't test since they are not functional by themselves. i also noticed that some of the examples are copied word for word from the Adobe Guide book which is available for free on the adobe website. Overall i was disappointed with this book as it didn't teach me how to do anything.
