Thank You for Your answer!
You know, I had finished my aplication using secod option few seconds before
You answered me :). But still thank You very much for help.
But I have to tell You that I am little disappointed of the strategy using
in Struts. I was wating for some special controllers to help with my wizard,
but You show me that there is nothing like this :(. In the other hand maybe
it is better that it is so simple mathod :) ?
Thanx

Re: [S2] Collecting data from few pages
Posted by Michael Jouravlev <jm...@gmail.com>.
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.

Re: [S2] Collecting data from few pages
Posted by Laurie Harper <la...@holoweb.net>.
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.)
