Out of the two options outlined by Laurie the first is the proper one ;-) The second option works for sequence of pages, but not for a wizard. A wizard is a single stateful object with multiple views depending on wizard state. A page sequence is just sequence of web resources/pages not necessarily corresponding to one particular state object.
You can build a bulletproof wizard by: * storing state in session; * using exactly the same URLs for all wizard views (including parameters); * using redirection between data input and page render. If you do all of this, many (most?) browsers will not accumulate wizard pages in their page history, so a user will not be able to click Back button and to return to previous wizard page. I user will also be able to use Reload button safely. Try this: http://downloads.sourceforge.net/struts/dialogs-samples-2.0.war?modtime=1141554060&big_mirror=1 Run it and see Multiple-step wizard sample. If you like what you see, the source code is included ;-) Other choice is to use Ajax and to place wizard views into asynchronously reloadable HTML container. In this case it does not really matter how URLs look like and whether you use forwarding or redirection. Michael. On 2/12/07, Laurie Harper <[EMAIL PROTECTED]> wrote:
There are basically two options: retain the data from each page on the server side, or maintain it client-side as part of each request/response. For the first option, you can use a single form bean to aggregate the data from all the pages in your wizard and place it in session scope. You could also use some other strategy to retain the data between requests (e.g. storing it in your database as you collect it), but simply placing the form bean into session scope is probably the most straight forward way to go. For the second option, you would include hidden form fields on page2 for every item of data from page1; hidden fields on page3 for the data from pages 1 and 2, etc. Either approach (or some variant) will work. Which to choose depends on what constraints you have on your application (are you OK with using session-based storage? do you have a large amount and/or frequently changing set of data to collect? etc.) L. puchacz wrote: > They could...
