Re: Fwd: Re: Populating multiple forms from one action class

[Curtney Jacobs]

Greetings!!

I have solved the problem, quite simple really.

I was not associating the ActionForm instance to the form bean declared in my 
struts-config.xml file.

However, I would like a cleaner approach to doing the association. Currently, 
I have the following in my generic action class:

request.getSession().setAttribute("StudentForm", sForm);
request.getSession().setAttribute("GuardianForm", gForm);

Thanks in advance,

Curtney Jacobs

Greetings Craig!!

just to verify.

So, it is possible to populate multiple forms (contained on a single JSP
 page) from within one action class.

For instance, I intend to have one action class that pre-populates three form
beans: education, guardian, and enrollment.

Currently, I have the action class pre-populating only one form bean and
putting it into the current session, however, the data is not shown in the
form when the jsp page is displayed. It only work when I associate the action
to the form bean within my struts-config.xml

Thanks in advance,

Curtney Jacobs

Prepopulating input forms this way (by setting up the form bean in an
Action that preceeds the display of the form) is a very standard approach
in Struts based applications.  It's a perfectly reasonable thing to do.

Whether you do it with a generic Action, or a customized Action for each
type of form is pretty much up to you.

Re: Populating multiple forms from one action class

[Curtney Jacobs]

Greetings!!

I understand what you are saying. However,  I was thinking that  it might be 
possible to pre-populate the ActionForms with a generic action class (not 
tied to any particular form) and put them in the current session.
  
The following is an excerpt from "Mastering Jakarta Struts" that supports my 
idea.  



" if the sesion already includes an instance of the ActionForm named by  
the  element's name attribute, then the values stored in its data   
members will be used to prepopulate the input values. "



If anyone else have any opinions on this please don't be afraid to comment :-)

Thanks in advance,

RE: Populating multiple forms from one action class

[Sven Frederik Pohl]

Hi Curtney,

The forms could only be populated if the form data is send via the HTTP request. that 
only happens if the there is only one enclosing HTML form. Since (as far as I know) 
the  Tag is bound to exact one HTML form, I don't think that this is 
possible. You could possibly inherit one overall form from all the simple forms but 
you will run into problems with validation (hence only one validate method for the 
form) and the form name (the form extending all the other forms will be saved under a 
single overall name) and even properbly form bean property names if they interfere, so 
this does not seam a good approach to me. But you could try, or more straight forward 
use only one form for related fields that should be all populated together.

Hope that helps,

Sven

Greetings!

is it possible to populate multiple forms on the same jsp page from only one 
action class? 

I have three forms (more may be added later on) on one jsp page. Each form is 
associated with its own action class for updating (submit) data. However, 
when I select an employee I would like to populate all three forms 
simutaneously.

Thanks in advance,

Populating multiple forms from one action class

[Curtney Jacobs]

Greetings!

is it possible to populate multiple forms on the same jsp page from only one 
action class? 

I have three forms (more may be added later on) on one jsp page. Each form is 
associated with its own action class for updating (submit) data. However, 
when I select an employee I would like to populate all three forms 
simutaneously.

Thanks in advance,
