Hmm.. I saw the "beOptional" but wasn't sure what it did -- is that just
a flag that controls whether or not to use the optionalLabel or does it
do something else as well? I did miss however the #optionalLabel:
method. I'm not really sure what the #on: is doing -- it looks like an
alternative to #callback -- any comments on why its better? Is that
because I'm not specifying a #selected call and this one call does both?
