I'm trying to include <f:viewParam> and <f:viewAction> tags conditionally in my JSF pages with JSTLs <c:if> as I don't want to manually specify the viewParams in every single JSF page. Unfortunately it is not working...
metadata_include.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<f:viewAction action="#{detailsBean.onload}" />
</c:if>
</f:metadata>
</ui:composition>

</ui:include>
</h:head>
<h:body>

</html>
Anybody knows what I'm doing wrong or knows a different way how to achieve this kind of behavior?
I also tried it with <h:panelGroup rendered="#{detailsId eq 'true'}"> without success.

I am a beginner programming Java and I am doing a project using primefaces. I want to include another XHTML page in an XHTML page. The include page is in /WEB-INF/facelets/include.xhtml (It has some data from a Managed Bean)
In my "page.xhtml", at first, I put this line inside <ui:define name="content">:
<ui:include src="WEB-INF/facelets/include.xhtml" />
But, it does not work.
Later, I tried to do this inside <ui:define name="content">
<ui:include src="WEB-INF/facelets/include.xhtml">
<ui:param name="fullName" value="#{identityInformationBean.fullName}" />
</ui:include>
And in the "include.xhtml":
<h:outputText
rendered="#{fullName!=null}"
value="#{fullName}" />
But, it does not work too. Nevertheless, if I do this:
On "page.xhtml"
<ui:include src="WEB-INF/facelets/include.xhtml">
<ui:param name="fullName" value="Helen" />
</ui:include>
The "include.xhtml" receives the information correctly.
I'd tried to registering the include file as a tagfile, as suggest here How to include another XHTML in XHTML using JSF 2.0 Facelets?
But, it does not work.
Any idea to solve this problem? Thanks!
This is a piece of code from "include.xhtml":
<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<h:outputText

value="#{identityInformationBean.fullName}" />
</ui:composition>
This is a piece of code from "page.xhtml":

</ui:composition>
I'm not sure why you need ui:param. Think of the include file as just saving you the trouble of typing that included code into all the pages that might use it. You don't need to pass it a parameter.
What about using a single line of code: <ui:include src="WEB-INF/facelets/include.xhtml"/> And the include file would have <h:outputText value="#{identityInformationBean.fullName}"/>
After a year gap i have again started working in JSF and facing problem in the facelets usage Below is the maintemplate.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head>
<title><ui:insert name="title" /></title>
</h:head>
<ui:insert name="header" />
<body>
content
</body>
</html>
Below is the ui:composition of the other xhtml file
enter code here
<?xml version="1.0" encoding="UTF-8" ?>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui"
template="/index.xhtml">
<ui:define name="title"><h:outputText value="Please Sign In" /></ui:define>
<ui:define name="header"><h:outputText value="Please Sign In" /></ui:define>
</ui:composition>
the same content works with the ui:include but doesn't work with the ui:defin and ui:insert combination
I was using the tags in the wrong way need to include include tag inside the insert to get the correct template functionality
I have a little problem with JSF,
I've made simple JSF page to learn:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>register</title>
<meta http-equiv="Content-Type"
content="application/xhtml+xml; charset=UTF-8" />
</h:head>
<h:body>
<h:form>
<h:outputText value="Hello."/>
<h:inputText value="#{login.name}"/>
<h:outputText value="Password"/>
<h:inputText value="#{login.password}"/>
<h:button value="Getgreeeting" outcome="welcome"/>
</h:form>
</h:body>
</html>
And another page to show the values inserted to bean:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>welcome</title>
<meta http-equiv="Content-Type"
content="application/xhtml+xml; charset=UTF-8" />
</h:head>
<h:body>
<h:outputText value="#{login.name}"></h:outputText>
<h:outputText value="Yours password #{login.password}"></h:outputText>
</h:body>
</html>
I've made some System.out.println() methods and they present that only getters in my beans works. Can somebody explain me why? What is solutionof my problem?
The <h:button> is not a submit button. It's a navigation button. Look closer at the Hello World example in your book/tutorial/resource (if you have any ..). You need a <h:commandButton> instead.

So I have:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<h:body>
<ui:composition template="template.xhtml">
<ui:define name="content">
<h:outputText value="Test!!!" />
</ui:define>
</ui:composition>
</h:body>
</html>
as my main page on my website and on template.xhtml:
<div id="content">
<h:panelGroup layout="block" styleClass="centercss">
<ui:insert name="content" />
</h:panelGroup>
</div>
...in the middle of the footer and the header views.
Now if I try to change the template="template.xhtml" to template.jsf it does not appear anywhere... the way it is right now I get my 'content' page perfectly in the middle of header and footer on the eclipse preview, but on the browser there's no content at all.
Im using primefaces3.1.1 and I have javax.faces-2.1.14 + jsf-api and jsf-impl, so I think its primefaces 3 and JSF 2.
What is the problem here ?
I think you are using facelets (templating) in a wrong way. You should'nt have html and body tags on your main page. The page that will use the template must be defined in a <ui:composition> tag, and the template shall define the page as a whole (html, body, head tags, etc).
Example:
index.html
<?xml version="1.0" encoding="UTF-8"?>
<ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:p="http://primefaces.org/ui"
template="template.xhtml">
<ui:define name="content">
<h:outputText value="Test!!!" />
</ui:define>
</ui:composition>
template.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:body>
<div id="content">
<h:panelGroup layout="block" style="background-color: red;">
<ui:insert name="content" />
</h:panelGroup>
</div>
</h:body>
</html>
I have such situation situation:
in file form.xhtml i have form used for filter some tables, i gave button "filter" defined here.
in file tableOne.xhtml, tableTwo.html, .. i have dataTable with id "filterTable", i've also included form.xhtml into this page. all pages with dataTables includes form.xhtml and all dataTables on them have the same id "filterTable"
what i want to do is to update dataTable[#filterTable] on after filter button is pressed using ajax. button is created by <p:commandButton>. if form and datatable are defined in the same file, all i need is simply add update="filterTable" to my command bytton. but if i add it to button defined in form.xhtml i get "Cannot find component with identifier" error.
is it possible to dynamic update dataTables from outside xhtml files included on page? if it is, how can i do it?
Example:
test.xhtml:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<h:form id="dtForm">

</h:form>
<ui:include src="/include.xhtml" />
</h:body>
