It is used for decorating form fields when validation fails. 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.
