Dear all,
I was trying to going from one JSP page to another, where each JSP
page has a submit button... and a Form bean as well.
But when I click a submit button on the first JSP page, it said that
the second Form bean is not found in the second JSP page.
The workflow is supposed to be:
RedirectForm -> RedirectHelpForm
Can anyone please shed some light on me to resolve this issue?
Thank you very much in advance.
Here is the error:
02:26:27,748 ERROR [PortletRequestDispatcherImpl:316]
