[jboss-user] [JBoss Seam] - Seam selectItems ignores label tag

[hubaer]

Hello,

I tried to figure out how the selectItems component from seam works, but I wasn't very successful yet.

I tried out the examples but I can't figure out how I can transfer this to my application.

Here my scenario:

I have a List of Languages, that I want to display my web gui in a h:selectOneMenu.
I have extend my jsf, wrote a Converter, make a backing bean. The value of the option is set correct through the Converter, but for the description I get always the result of the toString() method. It seems that the label tag is ignored. I can write what ever I want and get always the toString()-result.
Maybe I have configured wrong.

Here some code fragements:

The jsp:

  | 
  | <h:selectOneMenu value="#{user.language}" converter="myLanguageConverter">
  |                         <si:selectItems
  |                             value="#{languages}" var="language" label="#{language.isocode}"/>
  |                     </h:selectOneMenu>
  | 

The backing bean:

  | public class EditUserInformationActionBean implements EditUserInformationAction, Serializable {
  |     
  |     @SelectItems
  |     private List<Language> languages;
  |     
  |     
  |     @Factory("languages")
  |     public void initLanguages() {
  |         languages = ItemHelper.initLanguage();
  |     }
  |     
  |     ...
  | 
  | }
  | 

The Converter:

  | public class LanguageConverter extends SelectItemsConverter {
  |     
  |     public LanguageConverter() {
  |     }
  | 
  |     public Object getAsObject(FacesContext context, UIComponent component, String value) throws ConverterException {
  |         throw new ConverterException("Method not supported");
  |     }
  | 
  |     public String getAsString(FacesContext context, UIComponent component, Object value) throws ConverterException {
  |         if (null == value) {
  |           return "";  
  |         }
  |         if (value instanceof Language) {
  |             Language l = (Language) value;
  |             return formatLanguageString(l);
  |         }
  |         return ""; 
  |     }
  | 
  | 

The language class:

  | public class Language implements Serializable {
  | 
  |     @Id
  |     @Column(name = "isocode", nullable = false)
  |     private String isocode;
  |     
  |     /** Creates a new instance of Language */
  |     protected Language() {
  |     }
  | 
  |     // getter/setter, toString, equals etc.
  | 



The examples works fine. But I think there is an litte error, too. The discount drop-down-field has the descriptions "tenPercent", ""twentyPercent" and "twentyFivePercent", but I would expected the values from the message.properties (10%, 20% and 25%)

I hope someone could give me a hint what's wrong.

My System:
- WinXP Pro
- JBoss 4.0.5.GA
- Seam 1.1.0.GA

Tried:
- selectitems-1.1.1beta4
- selectitems-1.1.0rc2
