Hi, I am using an attribute in APPLICATION scope for concurrency checking. The problem is, the attribute has to be reset if (and only if) the user navigates out of the page without submitting the data (say ,by clicking the BACK button in the browser) ... So ,how do i detect that?

That would likely require the use of javascript and the onunload property of the body tag. Do your validation in a script, then set the page URL to be a page that does what you need it to do. The problem is that there's no guarantee that the JavaScript will run as you expect it to on the client's browser... It might be best to reconsider your plan and look for alternate ways of knowing when to commit/rollback.
