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
