What to use to lookup label for a given value and just render the label ?

Question

Which component or function to best use to render a label as an outputText in a table regarding the value that is loaded from the iterator.
I'm searching for something like a lov but just to render the corresponding label as an outputText.
Does something exists in adf faces for that purpose.
Is selectOneChoice or showOneChoice the component to use ?
Is better to do this in a backing bean ?
Any recommandation will be mostly appreciate
Thanks

Hi,
let say in managed bean you have a list with values:public class MBean {
    public List getLanguages() {
        List langs = new ArrayList();
        langs.add("en");
        langs.add("sk");
        langs.add("fr");
        return langs;
}This   <af:panelGroup layout="vertical">
    <af:forEach items="#{MBean.languages}" var="lang">
      <af:outputText value="#{lang}"/>
    </af:forEach>
  </af:panelGroup>will display: en
sk
frNow let's make a lookup object. Add this map into your bean:     public Map getLangDesc() {
        Map myMap = new HashMap();
        myMap.put("en", "English");
        myMap.put("sk", "Slovak");
        myMap.put("fr", "French");
        return myMap;
    }and replace previous page content with:   <af:panelGroup layout="vertical">
    <af:forEach items="#{MBean.languages}" var="lang">
      <af:outputText value="#{MBean.langDesc[lang]}"/>
    </af:forEach>
  </af:panelGroup>The output is now English
Slovak
FrenchOf course lookup method should look different. This is just example. Now the map is recreated after each request.
