RE : ActionForm with Indexed Properties

[Franck Lefebure <fl...@orange.gp>]

Hi,
Finally, the way I feel the best is to put
the form in session scope when I create/modify it
and to get it from the session in the reset() method

I was inspired with the war example found here
http://keyboardmonkey.com/downloads/index.jsp
