Actually no, the method is not invoking super.handleRequestException() . I coded it along the lines of "Version 3: Decorating the RequestExceptionHandler" at http://tapestry.apache.org/overriding-exception-reporting.html and that example does not invoke the super method, but that's because the class does not extend anything, it just implements the interface: > public class RequestExceptionHandlerImpl implements RequestExceptionHandler So it sounds like I should not implement RequestExceptionHandler directly, but rather extend DefaultRequestExceptionHandler - which already implements RequestExceptionHandler - and then call super.handleRequestException() at the top of my handleRequestException() ... I'm going to try that, thanks for the pointer :)
