Arriving at a new page doesn't always mean they've left the first page -
they could have done an "Open link in new tab/window". Or they could
have just opened a new window and typed in a different url on the same
site. In both cases, the first page is still open in their browser.

when a new page is requested i.e. the user deliberately navigates away

I'm guessing that it should be should be do-able, if it's not possible
already?

Thiago,
PageDetached fires when the instance of the page used to service the
request
gets returned to the page pool. It doesn't have anything to do with the
user navigating away from a page.
The problem is, with Forward and Back buttons, navigating away from a
page
is a browser-side event. Different frameworks have tried various
ways to
stop the back-button from breaking applications. It's one of the big
reasons that T5 moved to the redirect-after-post pattern.

Hi,
Is there a hook you can leverage to trap an event when the user
navigates to a new page?
I didn't understand how different this situation would be from simply
catching the end of the rendering of a page. This would be the
@CleanupRender event or, maybe better, the @PageDetached event. All the
component events are described here:
http://tapestry.apache.org/tapestry5/guide/rendering.html and the page
events here:
http://tapestry.apache.org/tapestry5/guide/lifecycle.html.
