Description

The parameter for AjaxFallbackButton#onSubmit is Optional<AjaxRequestTarget> because the AjaxRequestTarget can be null. However, the parameter for AjaxFallbackButton#onError is AjaxRequestTarget. The AjaxRequestTarget can be null so the parameter to #onError should follow #onSubmit and also be Optional.
