I have hit upon the same problem as this thread, but I didn't see a resolution.
It seems that in Struts 1.0, there must be an ActionForm for every page that has a
form in it -- or, indeed, an ActionForm for every form, including one for each form on
a page.
I had thought that I could have an Action class that would read the FORM parameters
directly, but that I would not need an ActionForm for each screen.
(One of the goals for Struts 1.1 seems to address this.)
Is the above correct, or am I missing something?
Thanks.
