SelectOneMenu problem

Question

Hi,
I got the following setup:
appBean.java
=================
private ArrayList country;
public appBean() {
this.country = new ArrayList();
protected void init(){
List list1 = this.getMiscService().getAllCountriesServ();
for (i=0; i<list1.size(); i++) {
Country co = (Country)list6.get(i);
this.country.add(new SelectItem(Integer.toString(co.getId()), co.getName()));
register.jsp
============================
<h:selectOneMenu value="#{userBean.selectedCountry}" id="selectedCountry">
<f:selectItems value="#{appBean.country}" id="countries"/>
</h:selectOneMenu>
<h:message for="selectedCountry" styleClass="errorMessage"/>
userBean.java
=======================
private ArrayList selectedCountry;
public ArrayList getSelectedCountry() {
     return this.selectedCountry;
public void setSelectedCountry(ArrayList newSelectedCountry) {
     this.selectedCountry = newSelectedCountry;
When I clicked on submit, I got an error msg beside the SelectOneMenu:
" "selectedCountry": " Conversion Error setting value '1' for 'null Converter'.
I hv even changed to :
userBean.java
=======================
private SelectItem selectedCountry;
public SelectItem getSelectedCountry() {
     return this.selectedCountry;
public void setSelectedCountry(SelectItem newSelectedCountry) {
     this.selectedCountry = newSelectedCountry;
but still get the same error msg. Pls help !!

The "value" of your <h:selectOneMenu> isn't going to be the SelectItem instance itself. It'll be the "getValue()" result of the SelectItem, which is much more what you want in your model.
So:
For starters, change:
  this.country.add(new SelectItem(Integer.toString(co.getId()), co.getName()));to:
  this.country.add(new SelectItem(new Integer(co.getId()), co.getName()));unless you really want Strings. Then, change your selectedCountry code to:
private int selectedCountry;
public int getSelectedCountry() {
return this.selectedCountry;
public void setSelectedCountry(int newSelectedCountry) {
this.selectedCountry = newSelectedCountry;
