1 request & 2 forms
Hi.
Can i use the struts mechanism to fill 2 *different* action forms from 1
http request ?
I've a button in a .jsp page. When the user to press this button, i need
to save a session scoped form before forward to a new page (the new page
uses another form). Is is possible ?
Thanks.

Solved !
I don't know why but when i use multipart-form i get an error while
populating the second form (like the case of Guillermo). Then i've
removed enctype from html:form and everything works !
**Case 2** source.jsp -> AAction (AForm) -> BAction (BForm) ->
destiny.jsp (BForm)
Where AAction is only a org.apache.struts.actions.ForwardAction...
Thanks !

Struts fills Forms attributes before invoking an action.
How are you chaining these actions?
In case 2:
Source.jsp post to Aaction. Aform is populated with request parameters
and execute in Aaction is called. You do something with this and then,
returns an actionForward that as "Baction.do". So, you "chain" these
actions, and Struts is invoked again with this actionForward. The
request is the same (do not do any redirect) so Struts populates Bform
Asociated to Baction and fills it with the same request parameters as in
Aform.
Are you configuring mappings like this?
<action path="/AAction" type="mypackage.AAction" name="AForm">
<forward name="BAction" path="/BAction.do"/> <!-- if you use
redirect, request is lost and parameters are not filled.-->
</action>
<action path="/BAction" type="mypackage.BAction" name="BForm">
<forward name="destiny" path="/destiny.jsp"/>
</action>
May you are either calling Baction in other way or are using a redirect
between them, are you?
Cheers.
Guillermo.

Ok :-)
I have 2 .jsp files (source.jsp and destiny.jsp). Between these two,
i put an action (let's call it BAction). Either destiny.jsp and B action
were expecting a BForm. So :
**Case 1** source.jsp -> BAction (BForm) -> destiny.jsp
(BForm)
Now, i want to insert a new action (AAction) between source.jsp and
BAction. My AAction will use a AForm, like :
**Case 2** source.jsp -> AAction (AForm) -> BAction (BForm)
-> destiny.jsp (BForm)
But i want to struts automatic fills the properties of AForm and
BForm with the parameters from my http request.
I don't know why but, at case 2, when BAction receives BForm, its
properties have just null values...
Any glue ? I think i will use BeanUtils to fill the properties of
the second form (B form)...
Thanks !

Yes, i got a error.
I've just added a "org.apache.struts.actions.ForwardAction" (to struts
initializes and populates the session scoped form -> named A) between
the .jsp file (which contains the button) and a previous existent action
(the one which receives a new request scoped form -> named B). Now, the
attributes of B form are empty (i'm getting null values)...
Any idea ?

I have never done this but i don't see why not. When you press your submit
button on your jsp, an Action is called, right? You can do whatever you
want in that execute method would be my guess. So if you feel like saving
one form in session scope and another in in request attribute before you
forward to your new page, i don't see why you shouldn't be able to.. Do you
envision a problem?
