I am doing this (doing the GET to the action class to prepopulate the form)
and it works well but there was one interesting thing that happened
(assuming I have everything set up right). The validate() method in the
related form bean was called as well. Consequently, I am having to start
all of my validate() methods with:
if (request.getParamater("submit") == null)
so that I don't do edit checking on a GET ... No big deal, but am I missing
something?

Subject: Re: PrePopulating a form
The trick is to route control through an Action before display any JSP.
The Action does all the real work, like populating the form. The JSP
just displays the result.
