Example usage of SelectOneMenu In this example i want to use selectOneMenu to select a country from list of countries and save the country code for the user in USER_ACCOUNT table.

<h:selectOneMenu id="country" value="#{userForm.countryCode}" require="true">
	<s:selectItems value="#{countries.list}" var="country" label="#{country.countryName}"/>
	<s:convertEntity/>
</h:selectOneMenu>

In the above code “userForm.countryCode” refers to model “UserForm” with property countryCode, The helper class to load countries list is as follows , the scope is application as the countries and their code doesn’t change.

 @Name("countries")@Scope(ScopeType.APPLICATION)
 public class CountriesList {
 	@Outprivate List<country> list;
 	@In(create=true)  EntityManager entityManager;
 	@Factory("countriesList")
 	public List<country> getList() {
	 	Query query=entityManager.createNamedQuery("Country.findAll");
	 	list=query.getResultList();
	 	return list;
 	}
 	public void setCountriesList(List<country> list) {
 		this.list = list;
 	}
 }

Entity class Country is as follows,

 @Entity@Name("country")@Table(name = "COUNTRY")
 @NamedQueries({@NamedQuery(name = "Country.findAll", query = "SELECT c FROM Country c ORDER BY c.countryName"), @NamedQuery(name = "Country.findByCountryCode", query = "SELECT c FROM Country c WHERE c.countryCode = :countryCode"), @NamedQuery(name = "Country.findByCountryName", query = "SELECT c FROM Country c WHERE c.countryName = :countryName")})
 public class Country extends Model implements Serializable {private static final long serialVersionUID = 1L;
 @Id@Column(name = "COUNTRY_CODE", nullable = false)
 private String countryCode;@Column(name = "COUNTRY_NAME", nullable = false)
 private String countryName;
 public Country() {}
 public Country(String countryCode) {
 	this.countryCode = countryCode;
 }
 public Country(String countryCode, String countryName) {
 	this.countryCode = countryCode;
 	this.countryName = countryName;
 }
 public String getCountryCode() {
 	return countryCode;
 }
 public void setCountryCode(String countryCode) {
 	this.countryCode = countryCode;
 }
 public String getCountryName() {
 	return countryName;
 }public void setCountryName(String countryName) {
 	this.countryName = countryName;
 	}
 }
