When the JSF runtime encounters a composite component tag in a page, it follows these steps to create the top-level Java component that will serve as the root of the subtree of components In all of the following cases, it is assumed that the top-level component is a UIComponent that implements javaxfacescomponentNamingContainer and returns javaxfacesNamingContainer from its getFamily( ) method See if there is a component-type attribute on the <cc:interface> element If so, interpret it to be the component type of a component already registered with the JSF runtime and create an instance of that component

If there is no component-type attribute, look for a script-based UIComponent implementation that corresponds to the composite component Facelet page Sun s Mojarra implementation supports the Groovy programming language If Groovy is enabled, Mojarra looks for a file with the same name as the composite component Facelet page, but with the extension groovy, in the same directory as the composite component Facelet page, for example, trainer/ loginPanelgroovy If no such script can be found, create a fully qualified Java class name by taking the library name of the resource library that contains the composite component Facelet page and appending the dot character and the name of the Facelet page without the extension For example, trainer/loginPanelxhtml becomes trainerloginPanel In this case, we look for a Java class named trainerloginPanel and instantiate it, assuming it conforms to the previously stated requirements If no such class can be found, we simply ask the JSF runtime to create a component with the component type javaxfacesNamingContainer The <vt:loginPanel> component uses these rules to have the loginPaneljava file serve as the top-level component To see how this works, let s view the complete source for the trainer/loginPanelxhtml component We ll look at the interface section, and then the implementation section

<cc:facet name="loginOutcomeChoiceList" shortDescription="This facet should contain a menu of choices for where the navigation should go after a successful login"/> </cc:interface>
The POJO passed into the top-level component as the value of the model attribute must have the following Java methods: boolean userIdIsValid(String toTest) boolean passwordIsValid(String toTest) It must also have the following String JavaBean property: successOutcome Optionally, it may have a String JavaBean property: failureOutcome The using page markup may have a facet nested within <vt:loginPanel> named loginOutcomeChoiceList Here is the using page markup from the Virtual Trainer
<vt:loginPanel model="#{loginBacking}"> <f:facet name="loginOutcomeChoiceList"> <h:selectOneMenu binding="#{loginBackingloginOutcomeChoiceList}" > <f:selectItem itemLabel="Everyone's Events" itemValue="allEvents" /> <f:selectItem itemLabel="My Events" itemValue="myEvents" /> </h:selectOneMenu> </f:facet> </vt:loginPanel>
The Implementation Section for <vt:loginPanel>
This section makes extensive use of the binding attribute in combination with the #{cc} EL implicit object and the knowledge that there is a top-level component that implements specific methods The Java class will be shown following the Facelet markup
<cc:implementation> <h:panelGrid columns="3"> <h:outputLabel for="#{ccclientId}:userid" value="Userid:" /> <h:inputText binding="#{ccuserid}" required="true" requiredMessage="Userid is required" id="userid" /> <h:message for="#{ccclientId}:userid" /> <h:outputLabel for="#{ccclientId}:password" value="Password:" /> <h:inputSecret binding="#{ccpassword}" required="true" requiredMessage="Password is required" id="password" /> <h:message for="#{ccclientId}:password" /> <h:outputText value="On Login, Go To:" rendered="#{! empty ccfacetsloginOutcomeChoiceList}"/> <h:panelGroup> <cc:renderFacet name="loginOutcomeChoiceList"/> <h:commandButton value="Login" action="#{ccaction}" actionListener="#{ccactionListener}" /> </h:panelGroup> <h:messages for="#{ccclientId}" /> </h:panelGrid> </cc:implementation>

Building Custom UI Components
Note the for attribute for all the <h:outputLabel> elements This is essential because the label must have the absolute client ID of the actual Userid field, which, of course, depends on where you place the <vt:loginPanel> in the page This is why the top-level component must be a naming container, because it provides a naming scope for all of its children Next note all the binding attributes Recall from 7 that the binding attribute tells the system to use that EL expression as the way to get the actual UIComponent for the markup As you will shortly see, there are JavaBeans properties named userid and password on the custom top-level component that serve as the target for these binding expressions Next, note the conditional rendering of the On Login, Go To: text This text will only be rendered if the facet is actually provided in the using page The <cc:renderFacet> element can be included without any sort of conditional check because it will automatically take no action if there is no such facet Finally, and most important, notice the action and actionListener attributes on the button These attributes point directly to methods on the top-level component
