/**
* <b>DemoRequestAction</b><br>
* Oct 7, 2005<br>
*
* <b>Purpose:</b><br>
* This used to be DemoAction. We changed DemoAction to be a bunch of links, and leave
* it as an action in case we want to do something fancier with it later.
*
* This Action handles all the buttons for the Demo.jsp page.
*
* <p>
* This one is more complicated then usual since not all the actions require
* the form bean to be validated! I am going to have to hack a little bit to
* make that happen, I may end up making the form bean validation differ
* depending on the selected action.
* </p>
*
* <p>
* Buttons that make this action go:
*
* <ul>
* <li>
* Submit: submit the request specified by url and post fields (Should be done
* using Javascript locally)
* </li>
* <li>
* Change: select between the precanned demos
* </li>
* </ul>
*
* As usual we will have to uninternationlize the action name provided to us.
* </p>
