Hi,

Here is a simple example for setting values on page load.

My SEAM component is onPageload.

import java.util.Date;
import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.security.Restrict;

@Name("onPageload")
@Scope(ScopeType.CONVERSATION)
@Restrict("#{identity.loggedIn}")
public class OnpageloadAction  {
     
     Date today;

     public Date getToday() {
          return today;
     }

     public void setToday(Date today) {
          this.today = today;
     }
     
     public void initialize(){
          today = new java.util.Date();
     }     
}

Here is your XHTML page.

<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
                      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
     xmlns:s="http://jboss.com/products/seam/taglib"
     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:rich="http://richfaces.org/rich" template="layout/template.xhtml">

     <ui:define name="body">

          <h:messages styleClass="message" />

          <h:form id="login">
          
          <rich:calendar value="#{onPageload.today}" showInput="true" datePattern="MM/dd/yyyy"/>
          
          </h:form>
          
     </ui:define>
     
</ui:composition>

and finally your page.xml file.

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://jboss.com/products/seam/pages"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd">

     <action execute="#{onPageload.initialize}"/>
     
</page>

Hi Ambrish,

          Thanks a lot for your reply, I placed <action execute=""> tag in my page.xml. its working fine but problem is if i do any other action on the page its getting executed. Finally i solved this using seam remote component.

Regrads,
Senthil

<action execute="#{onPageload.initialize}" on-postback="false"/>

if you write on postback false this works only one times when loading page. It does not work any other actions. if you want to use this for list initilition you will like this.
