How to handle custom "SessionExpired"-exceptions in RAP (RCP is fine) [message #910831]

Hello,

I'm writing a singlesourcing application and have difficulties figuring out the exception handling mechanism in RAP.

In RCP I have registered a status handler which handles my custom SessionExpiredException by notifying the user that his session expired and then shutting down the platform (client). This is intended behavior.

In RAP I must handle this differently because of the multi-user environment. Can I register a status handler in RAP too? How would the status handler know in which browser to open the "session expired" dialog and then to redirect the browser to the login page?

Or what is a better way to implement this, with or without status handler?

Thanks,
Alex

If the status handler is called in the UI thread (I assume it is, since it handles uncaught exceptions in the UI thread) then you already know which browser is effected. Any UI code you execute will be in the context/session of the user who caused the exception.

Hello Chris, your solution worked just fine!

I tested this with two different users which are both logged in, one from Chrome, one from Firefox. I "killed" the session of the first user and he was notified and logged out. The second user was not affected.

So yes, the status handler catches the exception in the right context(UI Thread) and knows somehow which browser to notifiy.

Thank you, Alex.
