PrimeFaces button navigation action

I have a problem with navigating the pages through buttons.

My current xhtml snippet is like that:

<p:layoutUnit position="west" size="200" header="Menü" resizable="true" closable="true" collapsible="true">
            <p:column>
                <p:commandButton type="button" value="New Project" icon="ui-icon-document" action="#{createProject.create()}"/>


                <p:commandButton type="button" value="All Projects" icon="ui-icon-folder-open"/>

                <p:commandButton type="button" value="Edit" icon="ui-icon-pencil"/>

                <p:commandButton type="button" value="Delete" icon="ui-icon-closethick"/>

                <p:separator />
                <p:commandButton type="button" title="Yazdır" icon="ui-icon-print"></p:commandButton>
            </p:column>

        </p:layoutUnit>

Here, when I click on New Project it doesn't navigate to related page.

My beanfile:

  @ManagedBean
@RequestScoped
public class CreateProject {
    /**
     * Creates a new instance of CreateProject
     */
    public String create() {
        return "newproject.xhtml";
    }
}

How can I navigate user when the button is clicked?

edit: here is my faces-config

    <faces-config
    version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

have you tried using navigation-rule in faces-config - Mohammod Hossain

This code:

type="button"

makes commandbutton a simple javascript trigger. If you want to do anything on the server, you must remove type="button". Also, your method defined on action tag, must return a string corresponding to your desired view, and you don`t need yo use an xml for defining navigation. Have a nice day!

By default, commandButton component of the PrimeFaces, uses ajax to send the commands so navigations won't work. Set the ajax property to false:

<p:commandButton ajax="false" value="New Project" icon="ui-icon-document" action="#{createProject.create()}" />

Also make sure that your buttons are inside a form element. Put a <h:form> ... </h:form> around your whole <p:layoutUnit> tag.

Add into faces-config.xml

<navigation-rule>
       <from-view-id>page1.xhtml</from-view-id>
       <navigation-case>
           <from-outcome>page2</from-outcome>
           <to-view-id>/newproject.xhtml</to-view-id>
       </navigation-case>
    </navigation-rule>



@ManagedBean
@RequestScoped
public class CreateProject {
    /**
     * Creates a new instance of CreateProject
     */
    public String create() {
        return "page2";
    }
}

 <p:commandButton type="button" value="New Project" icon="ui-icon-document" action="#{createProject.create}"/>

I had the same problem. I solved it by using button instead of commandButton. Note that outcome is used instead of action.

 <p:button ajax="false" value="New Project" icon="ui-icon-document" outcome="#{createProject.create}" />

To perform an action when pressing a commandButton, you need to change:

<p:commandButton type="button" value="New Project" icon="ui-icon-document" action="#{createProject.create()}"/>

to:

<p:commandButton type="button" value="New Project" icon="ui-icon-document" action="#{createProject.create}"/>

without the "()"

The String returned by the method can either be a page (like your example) or a navigation rule (faces-navigation)
