Currently, there is a "bug" where if you pass an empty array to ChoiceList, then you get this following warning from `QuestionHelper::doAsk()`:

>
Warning: max(): Array must contain at least one element

That should probably be fixed too, but it would go on an earlier version, so I didn't want to mix fixes for different branches.

Thanks!
