You know what? I found the jump very easy and those guys at Adobe’s hq did a wonderful job on driving people into this new release of the Flex framework.
I’m not posting some code this time, just a link to a project which can be sooooooo helpful to take your dive: “Flex in a Week”.
Nothing hard, just take your time, your headphones and a good internet connection, drive your browser to http://www.adobe.com/devnet/flex/videotraining/flex4beta/index.html and start from the beginning…
If you’re not new to flex programming it will take you half a day to get into this new baby.
bye for now
