Your below is correct (at least from my understanding). My only point
is a developer shouldn't need to do this. EIther a) A tag should exist
that already supports this (similar to using html:options in Struts or
b) It should be easy to create you own selectItems while iterating
over the collection on the front end, similar to what you would do
with JSTL
