Help about h:selectOneListbox PLEASE!!!

Question

hi all
i have a strange problem when working with <h:selectOneListbox>
or <h:selectOneMenu> (I mean UISelectOne component).
When i select one item and submit it, it just work well, but after using another <h:selectOneListbox>
or <h:selectOneMenu> located in another page,
and making just two or three page navigation between these two pages,
without doing any changes to the <h:selectOneListbox>
or <h:selectOneMenu>,
the <h:selectOneListbox>
or <h:selectOneMenu> in the first or the second page doesn't remember its selected value.
here is the source code:
---------------------------------------------testHandler.java----------------
import javax.faces.component.*;
import javax.faces.model.*;
import java.util.*;
public class testHandler {
private List list = new LinkedList();
private Integer ival;
private Object oval;
public testHandler() {
list.add(new SelectItem(new Integer(1), "1"));
list.add(new SelectItem(new Integer(2), "two"));
list.add(new SelectItem(new Integer(3), "three"));
list.add(new SelectItem(new Integer(4), "four"));
public Object getOval() {
return oval;
public void setOval(Object oval) {
this.oval = oval;
public Integer getIval() {
return ival;
public void setIval(Integer ival) {
this.ival = ival;
public void setList(List list) {
this.list = list;
public List getList() {
return list;
