    selectManyCheckbox

    kelly goedert Apprentice

      Hi,

      I´m trying to populate a selectManyCheckbox and I´m getting the following exception:

      java.lang.IllegalArgumentException: Expected a child component type of UISelectItem/UISelectItems for component type javax.faces.SelectMany(j_id47). Found null.

      In my page I have:
      <h:selectManyCheckbox value="#{company.category}" required="true">
       <s:selectItems value="#{companyGeneralAction.categories}" var="cat" label="#{cat.name}"/>
       <s:convertEntity/>
       </h:selectManyCheckbox>
      
      My "company" bean has an attribute like this:
      
      
       private Set<EntityCategory> category;
      
      
      
      The EntityCategory is a entity bean like this:
      
      
      @Name("entityCategory")
      @Entity
      
      public class EntityCategory implements Serializable {
       private static final long serialVersionUID = 1L;
       private Long id;
       private String name;
       private Set<Company> entity;
      
      
      
      And in my session bean I have:
      
      
      @Name("companyGeneralAction")
      @Stateful
      @Scope(ScopeType.SESSION)
      public class CompanyAction implements ICompanyAction {
       @In(required = false)
       @DataModelSelection
       @Out(required = false)
       private Company company;
       @In(required = false)
       private RegistrationType registrationType;
       @Out(required = false)
       private List<EntityCategory> categories;
       @DataModel
       private List<Company> companyList = new ArrayList<Company>();
       @In
       private EntityManager entityManager;
      
      
      
      What I want is to populate a select many checkbox with all the EntityCategory elements I have in the database. Where I´m going wrong here?
      
      Thanks
