Hi, Both IRequestCycleSettings and IExceptionSettings have setter/getter for org.apache.wicket.settings.IExceptionSettings.UnexpectedExceptionDisplay. Only the latter getter is really used in DefaultExceptionMapper.
I'll remove the setter and getter in IRequestCycleSettings in 6.0 and mark it deprecated in 1.5 unless someone gives a good reason to keep them. -- Martin Grigorov jWeekend Training, Consulting, Development http://jWeekend.com
