Is there a downloadable document that describes the roListScreen; or is it time to abandon any downloaded documentation and refer to the online docs only?
I recommend you stick to the online documentation (also known as "the wiki" or "the confluence one"), it is being updated on-the-fly and is the most current one. Since a year ago or more, no formal PDFs are being cut on releases but even if they were, they'd age fast. So the wiki is a good thing.
Note i can't say "throw away the old PDFs", since not everything has been transferred faithfully - recent examples, list of language reserved words and screensaver doc were/are missing. But those are rare exceptions, your first stop for docs should be http://sdkdocs.roku.com/
and only after that consult more obscure sources (this forum included by the way - some things can be learnt only here, shhht).
