• ... know nothing about Flex.
• ... have programming experience.
• ... know XML, we will be seeing lots of it.
• ... have downloaded and installed Flash Builder 4 Beta 2.

Hello World:(Edit)

Why?(Edit)

Somehow after a year working as Community Manager at Adobe, I found myself needing to learn Flex all over again from Scratch. To help me learn Flex 4, I decided to create this wiki in parallel as I learn. As I publish new pages in the wiki, I am learning too. Hopefully many will find the end result valuable.

I hope you enjoy Learn Flex 4 from Scratch!

Cheers,
