Usage rule

cErrorHandler is used separately or as a middle or end component in a Route. If this component is used separately, it will handle errors in all sub-routes. If this component is used in the middle or end of a sub-route, it will only handle exceptions that happen in the components of this sub-route, either before or after the cErrorHandler.
