      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>
