problem with page parameter and back

henrik.lindberg May 26, 2007 9:19 PM

I am using a page parameter (I have a search result that is displayed, the user clicks on a link with a parameter being the id of a document to view).

Everything works fine as long as the user is "moving forward" - i.e. display something, then search again, select something etc.

But, if user hits back button, and selects a row from the same resultset the previously displayed document is displayed again.

Debugging this I noticed that even if the user clicks on a link with a different parameter - the method that is called to set the page parameter is called with the value of the previous setting of the page parameter.

Confused... Can someone help?

The weirdest thing is that I can go back once, and select something else, but if I go back a second time and pick (a third choice), the second choice gets stuck.

It looks like others have the same problem: http://jira.jboss.com/jira/browse/JBSEAM-660 - here Gavin points out that this is a JSF problem.

I am stuck on this issue - appreciates if someone has ideas what I should do.

If anyone is interested...

I had to provide a fix, so I added a urlrewrite call to pick up the parameter I needed, lookup the component that needed the parameter before forwarding the request to the seam page. My "filter" sets the property directly on the component . I then removed the page parameter from the declaration.

Bingo.

Your problem is not exactly the same as the one in the JIRA issue.

But I believe that your problem is already fixed in CVS, please try it out, thanks in advance for your help.

Oh, maybe I'm wrong. It probably is just the same problem in the JIRA issues.

(Which is also fixed in CVS, by the migration to JSF RI.)

Thanks Gavin - good to know it is (probably) fixed in the latest on CVS. If I understand, going to the latest in CVS, it also means switching to JBoss 4.2 - and possibly other changes as well.

I will do a more orchestrated change over at some point and then test everything. This thing bit me right now, and I had to fix it without introducing too many changes elsewhere.
