Rich,
There are alot of people out there that know flex better than me, like Mansour, Dasa, and other API team members. I got my start in programming well over a decade ago in Visual Basic, then Avenue (ArcView 3 proprietary language). I then moved to .Net and to JavaScript. I would say that JavaScript is the closest to Flex syntax. Anyway I have always been one to look at samples and have to know why they work and follow every path the code takes to see why it does what it does. I guess interrogating code is what I am best at, and what make me a successful programmer. So my best advice is don't just copy and paste code interrogate the codes logic and figure out why it does what it does. Also Google is one of my best friends 🙂
