This is true. You could infer some MXML structure based on the AS3 code, but it would be complicated to do. >>. Any Flex programmer will, in fact, know >> AS3 because you can't write a useful Flex app with MXML alone. This is true as well. Not that I am a complete pro at Flex, but I have found you want to know both MXML and Actionscript fairly equally. On large projects, I spend more time in Actionscript, but having the MXML makes life much easier and is important to make use of, MXML can save you a lot of time and headaches. I do think there are uses for MXML that are non-visual though, like setting up a webservice connection, describing effects (which I guess you could argue is visual, but it not a "layout" thing) or even loading XML, but for the most part, I think you're right. MXML for the view - what you see, and Actionscript for most everything else. You can even write arrays and stuff with MXML but I've never seen a good reason for that.
