Sure, what you do is: - Store a token - Integer, String, enum, anything you want, that indicates what page you're on, just like you're doing now. As you know, this will be restore when the back button is hit.
- In addition to storing that token right on the pageFlowScope, also set it into a one-element array on the pageFlowScope - but don't create a new array each time, just keep writing into that first element. The one-element array will *not* be restored to its prior state, because it's still the same instance. Consequently, when you go back a page, you'll see that the token directly on the page won't match the token within the array. Back button detected! You could encapsulate this strategy into a reusable object if desired. -- Adam On 6/11/07, D. Cardon <[EMAIL PROTECTED]> wrote:
Thanks, that clarifies the documentation. So, my follow-up question would be: Is there any way that I can detect in Trinidad that the user has gone from one page to the next one and then back again?
