The documentation says to import the neccesary classes for code completion etc. But that doesn't work, because the classes aren't on disk, they reside in the components that you can put in your library.
But flashDevelop can't use/'see' those (or at least, not that I know of)
If any of you are using FlashDevelop, and are able to use the code completion, I'd be very interested to know how you pulled it off
