[jira] [Commented] (WICKET-6240) Hook method to display more information on ExceptionErrorPage

["Martin Grigorov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-6240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15469995#comment-15469995 ] 

Martin Grigorov commented on WICKET-6240:
-----------------------------------------

The recommended way to do this is to register custom IRequestCycleListener and override its #onException() method.
If the exception is IWicketInternalException then return null, otherwise return RenderPageRequestHandler with a custom page that renders all the information you need.
I guess we have to improve the documentation.

> 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.
