[Trinidad] Session is about to expire dialog
Hi,
I am currently using a servlet filter to handle session timeouts to redirect
the request to a session expired page. This is working okay except for if
the user clicks on the chooseDate calendar icon after the session times out.
With ENABLE_LIGHTWEIGHT_DIALOGS="false" (due to the month name problem in
IE6 (Trinidad-941)), the session expired page appears in the calendar window
instead of the main window. Once approach to handling this case as well as
providing the user a warning before the session is going to timeout is to
display a dialog to the user prior to the session timeout that says
something like, "Your session is about to timeout" with a Continue button.
After a minute or two, the dialog would automatically be cleared and an AJAX
call would be made to the server to force the session expiration. To do
this, I would have to have a JavaScript timer that would be started when the
page is loaded, reset whenever a PPR call is made, and cleared whenever the
page is unloaded. Has anyone implemented this with Trinidad? Is there a way
to get notified via a callback or hook method when a PPR request is made by
the Trinidad JavaScript API? Correctime if I'm wrong, but I don't think I
can use the Trinidad dialog framework for this because it must be
implemented for every page in the application.
Thanks,
Richard

Andrew,
Thanks. It looks like addStateChangeListener(myCallback) should do the
trick.

Re: [Trinidad] Session is about to expire dialog
Posted by Richard Yee <ri...@gmail.com>.
I do need a hook into the Trinidad PPR mechanism so that I can reset the
timer whenever a PPR call is made. This will effectively refresh the
session.

I see. So it's not that you need a hook into Trinidad's ppr mechanism
so much as you want to generate a ppr request yourself using Trinidad's
apis. Does that about sum it up?

Re: [Trinidad] Session is about to expire dialog
Posted by Richard Yee <ri...@gmail.com>.
The client side code would involve using a JavaScript timer that is created
using the standard setTimeout(expression, timeout) call. This timeout period
would be slightly shorter than the timeout period that is set on the server.
The expression argument would call a function to display the "Session is
about to expire dialog". Once the dialog is displayed, another timer is
created that will clear the dialog and cause an AJAX call that would invoke
a servlet to expire the session on the server if the user doesn't respond
within a short amount of time. If the user clicks the "Continue" dialog
button, an AJAX call is made to a servlet that will refresh the session.
This is how many online banking applications handle session timeouts.

I guess I'm confused as to how the code on the client side would know
the session is about to expire without doing a ppr?

I think it is there since the old adf faces days. Perhaps we want to
change that but I think that is low priority

I believe the jar doesn't matter for JavaScript. I think that anything
that doesn't start with an underscore is public and anything that
starts with an underscore is not part of the API. Could someone
clarify on this?

Hey Andrew,
I did not know it was documented in devguide... Thanks for pointing it out.
It lives in trinidad-impl, so I assumed it was not part of public API.
In ADF Faces, we put all public JS functions/classes in the API jar.
I can see that all Trinidad javascript lives in the IMPL jar. Do you know if
it was intentional? I am copying Matthias too since he may comment on that.
Thanks,
Max

Max, it is part of the public API. It is clearly documented in the
developer documentation:

Re: [Trinidad] Session is about to expire dialog
Posted by Richard Yee <ri...@gmail.com>.
Scott,
The poll component will not work because I don't want to invoke a PPR b/c it
will refresh the session. What I need is a hook into the Trinidad JavaScript
API like an "onPPR()" method that I can override to be notified when a PPR
request is made. The purpose of the dialog is to tell the user if they are
still in front of the screen that their session is about to expire and give
them the opportunity to refresh the session rather than have them do
something with the UI and then get redirected to a page that tells them that
their session timed out.
Thanks,
-Richard

Will the "poll" component in Trinidad do what your asking?
