Time for action – using SelectOneMenu with POJOs

In this section, we will demonstrate how to use SelectOneMenu backed by a collection of POJOs by using a converter, by performing the following steps:

1. Create a SelectOneMenu component using List<Tag> POJOs:

   <p:selectOneMenu value="#{selectionController.selectedTag}" converter="tagConverter">  
       <f:selectItem itemLabel="Select One" itemValue="" />  
       <f:selectItems value="#{selectionController.tagPojos}" var="tag" itemLabel="#{tag.label}" itemValue="#{tag}"/>  
   </p:selectOneMenu>

2. Initialize List<Tag> POJOs in the managed bean:

   @ManagedBean
   @RequestScoped
   public class SelectionController 
   {
       private List<Tag> tagPojos;
       private Tag selectedTag;
   
       public SelectionController() 
       {
       tagPojos = new ArrayList<Tag>();
           tagPojos.add(new Tag(1, "JavaSE", "java-se", "Java Programming Language"));
           tagPojos.add(new Tag(2, "JavaEE", "java-ee", "Java Enterprise Edition"));
    ...
