Actually, this seems to me to be the perfect opportunity to create a custom
tag. So far, I have only created tags to conditionalize our online help, but I
know that you can create tags for iteration. You could put in something like
this:
<mylib:List type="pull-down" source="USStates" />
and then code the corresponding Java class to blow this out into a full HTML
pull-down list box. Sure is a lot cleaner than putting in a bunch of <% %>
code. And a lot easier to maintain, too.
