[jboss-user] [JBoss Seam] - s:selectItems once again

The problem :

  | Validation Error: Value is not valid
  | 

I`ve searched the forum and I found that one way is to implement equals() and hashCode() method. So I did (well copy-pasted ;))

  | @Entity
  | @Scope(ScopeType.EVENT)
  | @Name("questionCategory")
  | @Table(name="QuestionCategories")
  | public class QuestionCategory implements Serializable {
  |     
  |     @Id @GeneratedValue
  |     private Long id;
  |     
  |     @NotNull @Length(min=3, max=100)
  |     private String categoryName;
  |     
  |     @OneToMany
  |     private List<Question> questionList;
  |     
  |     @Temporal(value = TemporalType.TIMESTAMP)
  |     private Date created;
  |     
  |     @Override
  |     public boolean equals(Object obj) {
  |         if (!(obj instanceof QuestionCategory)) {
  |             return false;
  |         }
  |         
  |         QuestionCategory c = (QuestionCategory) obj;
  |         return this.id == c.getId();
  |     }
  |     
  |     @Override
  |     public int hashCode() {
  |         int result = 17;
  |         
  |         result = 37 * result + this.id.intValue();
  |         
  |         return result;
  |     }
  |     
  |     /** Creates a new instance of QuestionCategory */
  |     public QuestionCategory() {
  |         this.questionList = new ArrayList<Question>();
  |     }
  |     
  |     public QuestionCategory(String categoryName) {
  |         this.categoryName = categoryName;
  |         this.questionList = new ArrayList<Question>();
  |     }
  |     
  |     public Long getId() {
  |         return id;
  |     }
  |     
  |     public void setId(Long id) {
  |         this.id = id;
  |     }
  |     
  |     public String getCategoryName() {
  |         return categoryName;
  |     }
  |     
  |     public void setCategoryName(String categoryName) {
  |         this.categoryName = categoryName;
  |     }
  |     
  |     public List<Question> getQuestionList() {
  |         return questionList;
  |     }
  |     
  |     public void setQuestionList(List<Question> questionList) {
  |         this.questionList = questionList;
  |     }
  |     
  |     public Date getCreated() {
  |         return created;
  |     }
  |     
  |     public void setCreated(Date created) {
  |         this.created = created;
  |     }
  | }
  | 

I have a following code in my question.xhtml

  | <body>
  |         <h:form>
  |             <h:outputText value="Choose existing category: "/>
  |             <h:selectOneMenu value="#{questionCategory}" required="true">
  |                 <s:selectItems value="#{questionCategoryList}" var="category" label="#{category.categoryName}" noSelectionLabel="Please Select..."/>
  |                 <s:convertEntity/>
  |             </h:selectOneMenu> 
  |             <h:commandButton type="submit" value="Add Question" action="#{QuestionCategoryController.addQuestion}"/>
  |         </h:form>
  |     </body>
  | 

And quess what, this still doesn`t work !
