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

Phil
