[jboss-user] [JBoss Seam] - Problem with s:convertEntity

[Seto]

When I choose one of the category, nothing happen. But when i choose the no selection label, the form is submitted normally. Anyone could help me? Please, I'm waiting anxiously online now.

  | 
  | 	<h:form>
  | 		<s:validateAll>
  | 			<h:messages globalOnly="true" />
  | 			<h:panelGrid columns="2">
  | 				<h:outputText value="tag />
  | 				<h:inputText value="#{brand.tag}" required="true" />
  | 				<h:outputText value="name" />
  | 				<h:inputText value="#{brand.name}" required="true" />
  | 				<h:outputText value="category" />
  | 				<h:selectOneMenu value="#{brand.category}">
  | 					<s:selectItems value="#{categoryList}" var="category"
  | 						label="#{category.name}" noSelectionLabel="please choose" />
  | 					<s:convertEntity />
  | 				</h:selectOneMenu>
  | 			</h:panelGrid>
  | 			<h:commandButton value="new" action="#{brandHome.persist}"
  | 				rendered="#{!brandHome.managed}" />
  | 			<h:commandButton value="edit" action="#{brandHome.update}"
  | 				rendered="#{brandHome.managed}" />
  | 			<h:commandButton value="delete" action="#{brandHome.remove}"
  | 				rendered="#{brandHome.managed}" />
  | 		</s:validateAll>
  | 	</h:form>
  | 

  | 	@SuppressWarnings("unchecked")
  | 	@Factory
  | 	public void getCategoryList() {
  | 		entityManager.clear();
  | 		categoryList = entityManager.createQuery("from Category category")
  | 				.getResultList();
  | 		Contexts.getSessionContext().flush();
  | 	}
  | 

  | 	<factory name="brand" value="#{brandHome.instance}" />
  | 	<fwk:entity-home name="brandHome"
  | 		entity-class="com.hongyang.domain.directory.Brand" />
  | 

  | 	@ManyToOne
  | 	@JoinColumn(name = "category")
  | 	private Category category = new Category();
