Help! Problem with "isTokenValid"

[t t <wa...@yahoo.com>]

Hi, all,

I have a Form in my application, when user click the
"submit" button, an Action class will be called. There
is some code like this in these class. The first time
the user click the button, the error
"error.transaction.token" was shown while the second
time it's ok. Why?
Thanks in advance!
Tong

if (!isTokenValid(request)) {
            errors.add(
                ActionMessages.GLOBAL_MESSAGE,
                new
ActionMessage("error.transaction.token"));
        }
          |
          |
          |

if (!errors.isEmpty()) {
            this.saveErrors(request, errors);
            this.saveToken(request);
            return (mapping.getInputForward());
        }

You need 2 actions.  The first saves a token, then displays the form.  
The 2nd action is called when the form is submitted, and the code below 
looks ok.

I assume you either don't have an action to populate the form (eg the 
user opens the .jsp form directly), or the action does not save the token.

When your action to process the form checks for a valid token, the token 
doesn't exist, so it is invalid and you return your error message.
