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 !
I need help !!!
