Flex is very difficult to use for anything but the trivial.
Not because there are hundreds of lines of code needed. In fact,
there are often very few. The problem is, none of us know what
those lines of code should be. There is just not enough
documentation on FLEX APP building. The charting documentation is
probably the most lacking. But the event handling and localization
support are painfull as well.
Hope to see some better documentation... or books in
