newbie-question: validation across multiple pages

["Sebastian F. Martin" <me...@sebastianmartin.net>]

Hi all,

I've been studying the mailing list but couldn't find anything that
would help me. I'd be grateful if someone could give me a hint on this:

I am collecting user input across multiple pages and validate it in the
validate() method of the ActionForm. If an input field on the second or
the third page is empty after submit, the framework will take me back to
the first page. How can I make him turn me back to the page where the
input field was left blank?

Greetings
Sebastian

You might want to use session to store all the values entered in page=1.
Then when there is an error in page=2 or page=3, and forward the control 
back to page=1.  Since all the values are session scope, you can access them
in your page=1.  Remember you have to clean the session though:).

	if(! errors.isEmpty()) {
		...
		return (new ActionForward("page1"));	
	}
