Uncaught Exception Handling

Timothy Neill
6 years ago Jun 28, 2016 5:06pm

This is a duplicate question / thread, however the previous posts are now dated. I am wondering have there been any developments pertaining to best practices for this. 

What is the best way to define / set a handler for uncaught exceptions:

At main UI?:
UI.getCurrent().setErrorHandler(new CustomErrorHandler());

Or on session level?:
VaadinSession.getCurrent().setErrorHandler(new CustomErrorHandler());
 
What are the benefits of each? Should one register a handler with both the Session & UI in an init() method?
