Re: Loosing request attributes

Fri, 13 Aug 2004 08:36:08 -0700

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?

So i need them back in that page if validate fails.

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 :-( ???

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?
