    I changed the bean to request and now have this issue.

      I changed the bean to request from session bean and now have an issue.

      <rich:dataGrid id="membersInZipcode" value="#{membersInZipcode.arrayListOfSearch4Member}"
       var="membersInZipcode" columns="5" elements="20">
       <f:facet name="footer">
       <rich:datascroller></rich:datascroller>
       </f:facet>
      
       </rich:dataGrid>
       </h:form>
      


      I am using a request bean to hold the search parms that loads the bean. This works great.

      The problem is when I use the rich:datascroller for the next page.
      It goes back to the bean and the request scope bean is empty. This holds the search values.

      How do I put this back into the request after each process??

      Can this work with a request bean instead of session bean? I had a session bean but this was bad. When the user tried another search the bean had preselected values from last search in session bean. I was removing the session bean and putting it back into session like this...

      <%
      FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove("SearchFormBean");
      FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("SearchFormBean", new SearchFormBean());
      %>
      


      That did not work all the time either.

      Any help out there????

      Thanks
      Phil

          Hello Phil,

          You can try using a4j:keepAlive component.

            Thanks for the quick reply.

            I put this in my jsf page.

             <h:messages layout="table" showDetail="true" style="color: red" />
            
             <a4j:keepAlive beanName = "#{SearchFormBean}"/>
            
             <h:form id="f1" >
            


            package com.myApp.java;
            
            import java.io.Serializable;
            
            public class SearchFormBean extends Object implements Serializable{
             private static final long serialVersionUID = 7287950280019980982L;
            
            
             private boolean freeMembers = true;
             private boolean verifiedMembers = true;
            
             private String memberHeightFeet = "5";
             private String memberHeightInch = "0";
            


            I get this error..

              Works Great !!!!

              Thanks a ton guys....

              I changed.

              <a4j:keepAlive beanName = "#{SearchFormBean}"/>

              To this..

              <a4j:keepAlive beanName = "SearchFormBean"/>


              Thanks again this will help keep memory requirements down with less session beans. Also it works correctly..!!

              Thanks
