I tried using the example of showcase tuts from primefaces.org. I copied exactly the same text in my xhtml file as well as TreeBean.java
But The tree structure never appears in the browser(m using IE9). An empty block appears instead of the tree. Is there anything I need to keep in mind when using tree nodes?

You have to create and copy a TreeBean class too. It is avaible for every example on primefaces showcase site, next to xhtml's source code. To make it visible for EL you have to additionally annotate it #Named or #ManagedBean, and give it some reasonable lifecycle scope.
//EDIT:
#Named
#javax.enterprise.context.SessionScoped
public class TreeBean { ... }

I have a PrimeFaces <p:commandButton update=":messages" which doesn't display p:messages after sending the form, but if I use update="#all" instead it does update p:messages and I can see the messages displayed.
I've tried many other combinations such as update="messages", update="NewRegistryForm:messages", update="#form :messages", render=":messages"... but nothing else seems to work. Any idea why this might be happening?
On RegistryInputNewBean.processRequest I simply update the messages component like this:
FacesContext.getCurrentInstance().addMessage(
null,
new FacesMessage(FacesMessage.SEVERITY_ERROR, "", "error_processing_request")
);
mytemplate.xhtml, containing p:messages, is something like this:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"

<p:messages id="messages" showDetail="true" autoUpdate="true" closable="true" showSummary="false"/>
<ui:insert name="content" />
</h:body>
</f:view>
</html>
myform.xhtml is like this:
<!DOCTYPE html>
<html
xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"

<ui:define name="content">
<ui:composition template="mytemplate.xhtml">
<h:form id="NewRegistryForm">
<p:commandButton
id="sendButton"
type="submit"
action="#{registryInputNewBean.processRequest}"
update="#all"
style="display:none" />
</h:form>
</ui:composition>
</ui:define>
</html>
The p:messages is not inside a form, that is why the button is not going to update the component alone, only if you put #all, which refresh all the components in the page.
If you put another form that contain the p:message inside, you will be able to update the component with an update="fooForm:fooMessages"
you can update on the bean
Like
RequestContext rc = RequestContext.getCurrentInstance();
rc.update("id");
I have an application that has a layout with left and center layout units (demoLayout.xhtml). On main page (main.xhtml) i have p:tree on left layout unit (demoTree.xhtml) and three different forms on center layout unit (first.xhtml, second.xhtml, third.xhtml). Center forms switches using tree node clicks. My default center form is first.xhtml and when i do not put p:commandButton on first.xhtml command buttons on second.xhtml and on third.xhtml actions has not being called. When i put p:commandButton on first.xhtml the other command buttons works, but i do not want to put p:commandButton on first.xhtml. How can i do?

I also read these :
JSF : dynamically loaded page commandButton not working
Primefaces commandButton action attribute not being called
BalusC answer - h:commandLink / h:commandButton is not being invoked
This part from main.xhtml is the cause of your problem.
<ui:define name="center">
<ui:include src="#{demo3MBean.activePanel}" />
</ui:define>
changing value of src at runtime does not work.
Try it with a static value like
<ui:define name="center">
<ui:include src="third.xhtml" />
</ui:define>
and you will see that buttons work.
Changing value of src at runtime will not work.
<ui:define name="center">
<ui:include src="#{demo3MBean.activePanel}" />
</ui:define>
Alternative solution to conquer your problem is using a rendered flag for your xhtml pages.For example
<ui:define name="center">
<s:div rendered="#{demo3MBean.firstFlag}">
<ui:include src="first.xhtml" />
</s:div>
<s:div rendered="#{demo3MBean.secondFlag}">
<ui:include src="second.xhtml" />
</s:div>
<s:div rendered="#{demo3MBean.thirdFlag}">
<ui:include src="third.xhtml.xhtml" />
</s:div>
</ui:define>
Set all pages flag to FALSE intially. Make the specific flag value as TRUE only when the relevant tree node is clicked. Do not forget to set unique "id" of all components of the included pages.
Using the above solution, attributes like action and actionListener of components such as commandButtons, commandLinks etc will also work normally and perfectly.
Hope this will solve your problem.
And also do not forget to accept my answer if it helps. Have a nice Day!!
It is just impossible to include a different file by updating the form inside of the included file. As you have the form rightForm in each of your files, you are only updating the rightForm of the currently loaded file when a tree node is selected. So there will never be a different file loaded.
Besides it is a bad approach to define the same form in each file when it exists in everyone (similiar for the growl).
To fix this remove the h:form in first.xhtml, second.xhtml and third.xhtml and change the second ui:define in your main.xhtml to the following:
<ui:define name="center">
<h:form id="rightForm">
<ui:include src="#{demo3MBean.activePanel}" />
</h:form>
</ui:define>
And why are you defining three p:treeNodes in the p:tree? As you are initializing the tree in the DemoTreeBean there is no need to define the treenodes manually. The p:tree is just iterating through the nodes of the given value, as you can see in the showcase. Try the following code to reduce the effort when adding more tree nodes:
<p:tree value="#{demoTreeBean.root}" var="node" id="tree" animate="true"
style="width:350px;height:720px" dynamic="true" cache="false"
selectionMode="single">
<p:treeNode type="#{node.data}">
<h:outputText value="#{node}" id="lblNode1" />
</p:treeNode>
<p:ajax event="select" update=":rightForm" listener="#{demo3MBean.onNodeSelect}" />
</p:tree>
i just don't get it...
Why p:commandLink not working? The page is refreshing but with the same amount of data in table. I'm supposing that controller is okay. Take a look.\

You have multiple h:forms cascaded/nested, that's invalid html. Unknown/wanted side effects can/may occur, maybe like you are experiencing right now. Get right if that inner h:form and try again.
In your remove method, pf is the list which you return by calling #{warningsController.warns}?
I have a primefaces (version 3.4.2) slider and an inputText for output value of the slider value.
The problem is that a change of the slider update the displayed value of the inputText, but the setter bind to the inputText is not called.
Here is my slider:
<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:a4j="http://richfaces.org/a4j">
<h:head>
<title>Zinsrechner</title>
</h:head>
<h:body>
<h:form>
<h:panelGrid columns="1" style="margin-bottom:10px">
<p:inputText id="x" value="#{zinsrechner.monatlicherBeitrag}" />
<p:slider minValue="0" maxValue="150" for="x" />
</h:panelGrid>
</h:form>
</h:body>
</html>
And this is my Setter, which is NOT called:
public void setMonatlicherBeitrag( Double beitrag ) {
monatlicherBeitrag = beitrag;
}
The Getter IS called:
public Double getMonatlicherBeitrag() {
return GuiParameter.getSpareinlageProMonat();
}
Adding a <p:ajax> inside your Slider will to the trick.
Example:
<p:slider minValue="0" maxValue="150" for="x">
<p:ajax event="slideEnd" process="x" />
</p:slider>
I was facing the same problem, but in my case the thing was that I was setting the <p:inputNumber .../> label as read only. I removed that attribute and everything worked.
how to set layoutUnit header with f:facet. the following code is not working!
thanks
<p:layoutUnit position="west" resizable="true" closable="true" collapsible="true">
<f:facet name="header">my header</f:facet>
</p:layoutUnit>
use
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:pe="http://primefaces.org/ui/extensions">
<pe:layout>
<pe:layoutPane id="navigator-pane" >
<f:facet name="header">
</f:facet>
</pe:layoutPane>
</pe:layout>
from primefaces-extensions library
<dependency>
<groupId>org.primefaces.extensions</groupId>
<artifactId>primefaces-extensions</artifactId>
<version>1.2.1</version>
</dependency>
In primefaces the header of the layoutUnit is defined by the property header like that:
<p:layoutUnit position="west" header="HEADER" resizable="true" closable="true" collapsible="true">
</p:layoutUnit>
So, if you were using primeface-extensions then yes could change the header that way submitted by you.
