Just a quick suggestion. Couldn't you use javascript in your nav.jsp to submit the form in the intro.jsp? Or do you need form fields in the nav.jsp?

Firstly, the begin and end form tag must be in the same JSP. This prevents the tag from beginning in the 'body' tile and ending in the 'navigation' tile. There are other complications, even if I'm willing to compromise the design and place the <html:form> tag in the layout page (wizardLayout.jsp above).

This has a serious shortcoming in that it forces every body panel (i.e. every page in the wizard) to have knowledge of layout and therefore responsible for its maintenance. > > I really like the concept of Tiles and would love to use it to its fullest.
