I have an entity that contains email property: @Email private String email; This property is also subject to a unique constraint, which is coded in the backing bean: public void validateEmail(FacesContext context, UIComponent component, Object value) { | // some custom code that validates email uniqieness in DB... | } Now, when these two are combined in the view, the @Email constraint gets ignored: <s:validate><h:inputText value="#{selectedUser.email}" | validator="#{userController.validateEmail}" /></s:validate> Is this an expected behavior, or a bug?
