Modal combobox with Struts

[Leila Carvalho <le...@gmail.com>]

What is the best way to implement the logic of a second combobox that
depends
on the choice made in a first combobox in a JSP page, inside Struts
framework ??
For instance: if I choose EUA in the first combobox, the second combobox
must be
populated with EUA's states.  The same for countries X states etc.
Some people implement this with javascript, function onchange(). JSF uses
Events...
Thanks in advance!!

Yes, you need to use Javascript, apparently JSF has a wrapper on top
of a regular onchange.

If you need to load data from server on every change, then either use
Ajax, or reload the whole page after every onchange.
