Re: ActionForm field not changing when forwarded to Action

[Manish Singla]

You may not specify ActionForm in Action B. Thus struts request 
Processor will not reset values in Acion B.

This implies you have to create an instance of CommonActionForm in 
Action B. (See in which scope you are storing CommonActionForm in Action A).

Alterbate

You may also specify "attribute" in ActionMapping (for Action A) which 
will store bean in request/session scope. After that you have to  create 
instance in Action B

Thanks for this answer Manish,

what would you do if you need to change the value of one form parameter in
action A and you want to avoid this value to be lost after the forward to
action B ?
Is it possible to duplicate the actionform object in a "copy object" that
the Struts Request Processor wil not overwrite in Action B ?

Because when you forward to Action B, at that time Struts Request
Processor again processes Action Form. (FYI: In Action B, request is
still having old values from Form F. Thus, values are reset and populated)

Hi all

I have an application which exhibits two similar, yet distinct,

behaviours.

Behaviour 1:

Submit Form F to Action A.  In Action A change 1 (or more) of the fields

in

Form F.  Forward to JSP J.

Behaviour 2:

Submit Form F to Action A.  In Action A change 1 (or more) of the fields

in

Form F.  Forward to Action B.  Action B then forwards to JSP J.

The two behaviours are the same with the exception of the final

forwards.

The problem is that while the field value that's changed during

Behaviour 1

remains changed when JSP J is presented, the field value does not change
during Behaviour 2.
Does anyone know why?
TIA
