I remember having this discussion a couple of years ago. Since 12002 is a timeout error, it is unknown whether any changes were sent to the server. Thus it is not handled as a "connection error" which prompts the user to retry the request. Instead is just fails and the user gets the error message to restart the system.|
I'm afraid your only options are
(1) Track down the source of the timeout. Most likely it is a proxy server that is dropping the connection after a short time.
(2) Live with the timeout and subsequent restart of the app, and program your application to save the user's state so it can be restored quickly. There is a session store within RAP that is persistent across HTTP sessions.
Hope that helps,

RAP does not define any timeout. The timeout may be caused by the client
or the sever or anything in between like a proxy or router.
To print a more attractive error message is certainly possible, please
file an enhancement request therefore.
Continuing the broken user session however wouldn't make sense. The
client can't just ignore the missing response as it would bring client
and sever out of sync. Besides, before this message appears, the user
has the opportunity to retry sending the request.
Most browser have built-in tools or plug-ins to track requests that you
can use to analyze the failed request.
