    Creating a simple selectOneMenu

      Hi,

      I'm trying to use a selectOneMenu for a String property in an Entity. For example I have an entity with:

      @NotNull
@Column(name="Status")
@Length(max=16)
private String status;


      Instead of using a textbox for users to fill in this field i'd like to use a drop down with values that I populate. So I created the following h:selectOneMenu: 

      <s:decorate template="layout/edit.xhtml">
 <ui:define name="label">Status</ui:define>
 <h:selectOneMenu value="#{customerHome.instance.status}">
 <f:selectItem itemLabel="Active" itemValue="Active"/>
 <f:selectItem itemLabel="Inactive" itemValue="Inactive"/>
 </h:selectOneMenu>
</s:decorate>


      This works fine for submitting of the form. The selected itemValue will end up in the database. But when I want to view the data the proper selectItem is never selected. I know for example that #{customerHome.instance.status} contains the string "Inactive" but the form shows "Active".

      Any ideas how to fix that?

      Thanks,
      Felix

          i think this should be possible using s:enumItem and s:convertEnum,
          but you should also consider using a java-enumeration at entity-bean level:

          public enum CustomerStatus {
 INACTIVE,
 ACTIVE;
 public String getLabel() {
 return this.name(); //return whatever name you wanna see
 }
}

          then use this enum on your entity bean: 
           @Enumerated(EnumType.STRING)
 @NotNull
 public CustomerStatus getStatus() {
 return status;
 }

          then make the enum values available in the pages via a factory: 
          @Name("customerStatusFactory")
public class CustomerStatusFactory {

 @Factory("customerStatus")
 public CustomerStatus[] getCustomerStatus() {
 return CustomerStatus.values();
 }
}

          in your page, use the enum: 
          <h:selectOneMenu value="#{customerHome.instance.status}">
 <s:selectItems value="#{customerStatus}" var="cus"
 label="#{cus.label}"
 noSelectionLabel="Please select" />
 <s:convertEnum />
</h:selectOneMenu>

            Thank you very much for that answer. It works perfectly with your method.
