Catch exceptions without crashing app

Jester has a feature in which it catches exceptions of code without crashing the web application. How is this feature implemented. I have used the usual try and except for the proc and although it caught the exception the program still crashes.

Catch exceptions without crashing app

I wrapped the procedure in a template template safeRunning(action : untyped) = try: action except Exception as e: error(e.msg) Run then i called it here safeRunning:

I really can't find any part of the code that would be minimal enough to be tested. But i can give a example of an error i got which crashed the app although i have fixed it now. The was a value error which occured when i used parseFloat on a string(runtime error of course)
