Hey, When, during event handling, an uncaught exception is thrown, then Wt will print out the exception and terminate the session. The next request from the browser will then trigger a new session to be created, causing in a page refresh.
In your case, the exception that is being thrown is most likely an exception from Wt::Dbo that you don't have an active transaction while you are interacting with the database.
