Then this greater generality of interactive content possible in a .cdf
is a well-kept secret -- and contrary to the documentation!
In fact, the Mathematica 8.0.1 Documentation Center page
howto/CreateAComputableDocumentFormatFile
states:
"Almost all of the functions available in Mathematica can be used to
build applications for CDF Player, but there are a few programming
restrictions to keep in mind.
-- All interactive content must be generated with the Manipulate
command and may only use mouse-driven elements, such as Slider, Locator,
Checkbox, PopupMenu, etc."
Same thing is stated in the WRI web site version of that HowTo page.
