[Forums] Session Expiry

Hello Guyse,

I have one more problem like I want to cath exceptions and showing some user friendly messages.
e.g.
If I got an exception like of oracle ORA-01013 at the time of record update at this stage I want to show some kind if user friendly message.
on same page my session gets expired, I am used this session value at the time of record updation so I get another exception and i want to show some other message for user.
before go for update I want to check that session have its value or not but this thing gets automatically when session gets expire.


In asp.net or MVC we can have option to check session or show some popup message / notification message before session will get expired.
e.g. 20 sec before system will populate a popup will show session will get expired after 20 seconds. Once popup gets display timer gets from 20-0 once timer reach @0 page automatically redirected to home.

I am looking for same in outsystems.

I have posted 2 seperate questions
1] session
2] How to show multiple user friendly messages on exception basis on same page.
