Minor Description
Currently one of our customer is testing our application and every time an exception occurs he just copies the complete content of the ExceptionErrorPage into a ticket and forgets most of the times to include further information that we requested, e.g. a timestamp.
At the moment I'm using a custom ExceptionMapper to render a custom error page which enriches the existing ExceptionErrorPage with a few data from the session and a timestamp.
It would be nice if this could be done more easily.
Attached you will find a trivial patch which does exactly that: add a timestamp and provide a hook-method in the Application class which can be overwritten to provide more information which should be displayed on the error page.
