There are several facets: "beforeInvalidField", "afterInvalidField", "aroundInvalidField", (along with "beforeField", "afterField", "aroundField") that let you put decorations before, after, or around fields when a failure occurs. eg: | <h:form> | <f:facet name="beforeInvalidField"> | <h:graphicImage value="/attention.jpg"/> | </f:facet> | <f:facet name="afterInvalidField"> | <s:message/> | </f:facet> | <f:facet name="aroundInvalidField"> | <s:span styleClass="errors"/> | </f:facet> | | <div> | <s:decorate>Name: <h:inputText value="#{customer.name}" required="true"/></s:decorate> | </div> | <div> | <s:decorate> | Address: | <h:inputText value="#{customer.address}" required="true"> | <my:vaidateAddress/> | </h:inputText> | </s:decorate> | </div> | <div> | <s:decorate> | Email: | <h:inputText value="#{customer.email}"/> | <my:validateEmail/> | </h:inputText> | </s:decorate> | </div> | </h:form> | Then, when one of the fields is invalid, it will be shown in red with an image before it and the validation message after it.
