How are you instantiating the ProgrammingBasics class? Are you adding it to
the stage somehow with an addChild() after you create it?
It seems like you're using a book targeted for Flash. The Actionscript
syntax will of course be the same, but most of the patterns and practices in
it will probably make it harder to learn Flex if you're new to both of them.
I'd suggest googling for some Flex related ActionScript primers.
