Session

[Nadja Senoucci <se...@21st.de>]

Hello,

I have a more Java than Struts related question but maybe you could answer
it as well? Okay, so I use a link to get to a form. In the ActionForward
that gets executed when the link is used, I load an object and stuff it into
the session. In my form I then want the fields tp be prepopulated with the
data from the object in the session. As I understand it that happens via the
get-methods of the ActionForm class for this form. My question is: How do I
read the object from the session before my get-methods are called? As I
understood so far, I need the HttpServletRequest object for that - which I
only have access to in the validate method (which doesn't help, since that's
already too late)... I know there must a simple way to do this, I just don't
know how...

Greetings,
Nadja

(P.S.: Dirk, I think, I accidently send my Thank-you-reply for the help with
my stupid parsing problem to your email address. I just hit reply and didn't
look at the address the email would be send to... Sorry about that.)

In think this happens in your action? Why dont you call the setters of
your form at this time?

In the refering action that puts your object in the session, populate 
the form..

ActionForm theForm = (ActionForm) form;

Object yourObj = ...

String fooStr = yourObj.getSomething();

//for dynaforms
theForm.set("foo",fooStr);

or

//the method in your action form.
theForm.setFoo(fooStr);

//jsp

<html:text property="foo" />

there might be a more ninja way of doing this, but this is what i tend 
to do...

hope this helps

mark
