I need to create a layout like this but with all the containers on separated files, like:
top.xhtml
<p:layout fullPage="true">
<p:layoutUnit position="north" header="#{support.applicationTitle}">
<h:form>
<p:menubar>
<p:menuitem value="Quit" icon="ui-icon-close" action="#{userController.logOut()}" />
</p:menubar>
</h:form>
</p:layoutUnit>
Without the </p:layout>
because it will be close on my footer.xhtml like:
<p:layoutUnit position="south" header="© 2012 - 2012 PORTAL DE IDEIAS">
</p:layoutUnit></p:layout>
I have tried with both files but I get a error telling me that I need to close the layout tag, what is correct, but how can I solve my problem? Is this the best approach for a template? And another problem is that the layout tag require a center layoutUnit
This is indeed not the right approach. Your template has to be XML well formed. I suggest to create a master template file instead if all you want is to only specify the center unit.
Taking the example on the showcase site, that should look like this:
/WEB-INF/templates/layout.xhtml
<!DOCTYPE html>
<html lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui"
>
<h:head>
<title>Title</title>
</h:head>
<h:body>
<p:layout fullPage="true">
<p:layoutUnit position="north" size="100" header="Top" resizable="true" closable="true" collapsible="true">
<h:outputText value="Top unit content." />
</p:layoutUnit>
<p:layoutUnit position="south" size="100" header="Bottom" resizable="true" closable="true" collapsible="true">
<h:outputText value="South unit content." />
</p:layoutUnit>
<p:layoutUnit position="west" size="200" header="Left" resizable="true" closable="true" collapsible="true">
<h:form>
<ui:include src="../templates/themeMenu.xhtml" />
</h:form>
</p:layoutUnit>
<p:layoutUnit position="east" size="200" header="Right" resizable="true" closable="true" collapsible="true" effect="drop">
<h:outputText value="Right unit content." />
</p:layoutUnit>
<p:layoutUnit position="center">
<ui:insert name="content">Put default content here, if any.</ui:insert>
</p:layoutUnit>
</p:layout>
</h:body>
</html>
Note the <ui:insert>
in the center unit.
The template client can then just look like this:
/page.xhtml
<ui:composition template="/WEB-INF/templates/layout.xhtml"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui"
>
<ui:define name="content">
<p>Here goes your view-specific content.</p>
</ui:define>
</ui:composition>
which you open by http://example.com/contextname/page.xhtml.
