Hi All.,
In our application, I hava a list of tasks. Each task have a chech box and once checked the check box and click "AddAlert" button, alert for the checked task is created.
Up to this functionality working fine for me.

Thanks in advance.

I guess it is easier to repost, than to explain how to search mailing
list. Rick, Leon, you already have read this ;)
=== cut here ===
Tokens are better solution than nothing, but not the best. Token
works *after* POST request has been resubmitted. It can help to
prevent *data resubmission* on business/persisntence layer, but it
does nothing to prevent browser message: "Do you want to resend
POSTDATA?" What? What is POSTDATA? I don't care what it is, and I
don't know do I want to resend it or not, just show the damn page. The
simple "send POST, get page" approach results in horrible UI, like I
had to go through when I was ordering parts for my car. Car make->POST
form. Model->POST form. Year->POST form. Suspension part->POST form.
Struts (no put intended)->POST form -> (looking for Tokico struts,
don't see any). Go Back. "Do you want to resend POSTDATA?" - No -> I
see the same page. Back again. "Do you want to resend POSTDATA?" - Yes
-> The previous page is reloaded with the same POST, running the same
query on the server. Same happens three or four more times. I wanted
to strangle the programmer who desinged that. Right, if pages were
cachable, it would help. Or if I used Opera. But this is only one
example of many. In other cases Opera caching does not help, it gets
in the way.
Another example. You want to log in. You enter name, it is incorrect,
it is redisplayed. Again, and again, and again. You decided to drop
the idea, and to return back. How many times you need to click Back?
Also, token knows nothing about your business data. You are
shopping in the online store. You selected item, clicked "Add to
cart", it was added, and you forwarded to another page. Then you
realised that you need two of them. You click Back, see the same item
again and click "Add to cart". Now it tells you that you cannot do
this, because you are resubmitting the same request, apparently by
mistake. Your webapp can prove it to you, it has the freaking token.
But it is not a mistake, you actually want to add the same item again.
So, tokens better than nothing, like Yugo comparing to bike. But it is
still a Yugo.

what's wrong with this simple code
Posted by Vicky <ja...@yahoo.com>.
I don't see anything displayed on jsp with below
simple code in my struts action class.
MenuComponent mc = new MenuComponent();
mc.setName("Menu 1");
mc.setLocation("Menu 1");
mc.setTitle("Menu 1");
MenuComponent mc2 = new MenuComponent();
mc2.setName("Menu 2");
mc2.setLocation("Menu 2");
mc2.setTitle("Menu 3");
mc2.setParent(mc);
repository.addMenu(mc);
session.setAttribute("changeMgmtRepository",
repository);
///jsp
all required tag libs, imports in jsp and below code.
<body>
<div class="dynamicMenu tree">
<menu:useMenuDisplayer name="ListMenu"
repository="changeMgmtRepository">
<c:forEach var="menu" items="${repository.topMenus}">
<menu-el:displayMenu name="${menu.name}"/>
</c:forEach>
</menu:useMenuDisplayer>
</div>

Hello!
I would advise to use synchronization via Session tockens. (I'm working
at this process' automation at the moment). Struts' Action already has,
what is needed for this are saveToken() and isTokenValid() methods.
This technique makes it imposible to execute an action more then once
(if not on purpouse) exclueding double-submits, refreshes,
by-bookmark-visits.
Read the doc and check if that is what you need. And if yes, you can
take look in my two days old message titled "synchronization strategies"
- I beleave most answers (along with some questions :) ) are there.

Hello!
I would advise to use synchronization via Session tockens. (I'm working
at this process' automation at the moment). Struts' Action already has,
what is needed for this are saveToken() and isTokenValid() methods.
This technique makes it imposible to execute an action more then once
(if not on purpouse) exclueding double-submits, refreshes,
by-bookmark-visits.
Read the doc and check if that is what you need. And if yes, you can
take look in my two days old message titled "synchronization strategies"
- I beleave most answers (along with some questions :) ) are there.

simply send a redirect after executing create action to the list action
again?
