Loosing request attributes
Hi,
when a user request hits the ActionForm's validate
method and bounces back, i'm loosing some request
attributes that i had set for the page. In other
words, if the user inputs some data that don't pass
the validate method,
the page comes back with a few request scope
attributes missing.
Is there a way to avoid that this happens?

Erik,
i'm not talking about form attributes, that's what i
said in my last e-mail.
I'll try to clear it out.
Suppose a user submits a request that is handled by
MyActionDoSomething. Then this action sets a request
attribute like this:
request.setAttribute("MyObject", obj);
and forwards the request to the page
myPageDoSomeOtherThing.jsp, wich has some inputs for
the user to fill in.
This page (myPageDoSomeOtherThing.jsp) uses the bean
"obj" that was set in MyActionDoSomething.java ok !?
Now suppose the user submits wrong information in
myPageDoSomeOtherThing.jsp, what will cause the
validate method in the associated ActionForm to return
some ActionErrors. BUT when the ActionForm send this
page back for the user to re-input data, the bean
"obj" that was set at the very beginning in
MyActionDoSomething.java is NOT present anymore!
I think now it's clear that i'm not talking about the
formBean attributes, right !?

Re: Loosing request attributes
Posted by Erik Weber <er...@mindspring.com>.
You shouldn't have to do anything (in general, you rarely need to
implement reset) special for this. Struts does this for you. The user
submits the form. The form bean is populated with the user's input.
Validation starts on the form bean. Validation fails. Struts forwards
back to the input page, and the struts tags render all the values that
the user had input using the populated form bean.
Could you describe in more detail which types of form values seem to be
"missing" and which ones are intact? Is there a pattern to it?

RE: Loosing request attributes
Posted by Leandro Melo <lt...@yahoo.com.br>.
I don`t want to reset the attributes of my ActionForm
(what a form.reset() would do), BUT the attributes of
the request the were probably set by the Action that
forwarded to the specific page.
So i need them back in that page if validate fails.

Re: Loosing request attributes
Posted by Leandro Melo <lt...@yahoo.com.br>.
I was taking a look at the HttpServeltRequest and
ServletRequest apis and noted that theres a method
"getParameterMap()" wich returns a map of the
parameters, BUT there isn`t such a "setParameterMap()"
method.
So, what`s an automated way to re-set all my request
parameters in the ActionForm??? Do i have to go one by
one for each ActionForm :-( ???

Ensure that the request attributes are set in the ActionForm, this is
the only way that you can ensure that they'll still be there when the
validate fails.
