I have a custom InternalErrorPage, which I put into ApplicationSettings as follows:

getApplicationSettings().setInternalErrorPage(InternalErrorPage.class);
getExceptionSettings().setUnexpectedExceptionDisplay(
  IExceptionSettings.SHOW_INTERNAL_ERROR_PAGE);
getRequestCycleSettings().setUnexpectedExceptionDisplay(
  IExceptionSettings.SHOW_INTERNAL_ERROR_PAGE);

I want to display stack traces on this page (if I’m in development mode, of course). How can I do this?

    In Wicket 1.4 you can use 

    getRequestCycle().onRuntimeException(new MyErrorPage(), theException);

    Have look at the Wicket wiki and the mailing list for further explanations.

    In Wicket 1.5 onRuntimeException was removed. Instead you can

    “add your own org.apache.wicket.request.cycle.IRequestCycleListener (AbstractRequestCycleListener) with org.apache.wicket.Application.getRequestCycleListeners().add() and implement its #onException(RequestCycle, Exception)” (quoted from here)
