[jboss-user] [JBoss Seam] - DataModel edit issue

[rvkishore]

I am using the DataModel & DataModelSelection annotations to manage a datalist. The add and delete are working fine but the edit has a problem. The new values are not being submitted from the edit page into the Managers edit action. 

Below is my code


  | 
  | @Stateful
  | @Scope(SESSION)
  | @Name("sheetManager")
  | public class SheetManagerBean implements Serializable, SheetManager {
  | 
  | 	@DataModel
  | 	private List<Sheet> sheetList;
  | 
  | 	@DataModelSelection
  | 	@In(required = false)
  | 	@Out(required = false)
  | 	private Sheet sheet;
  | 
  | 	@In
  | 	private User user;
  | 
  | 	@PersistenceContext(type = EXTENDED)
  | 	private EntityManager em;
  | 
  | 	@Factory("sheetList")
  | 	public void findSheets() {
  | 		sheetList = (List<Sheet>) em.createQuery(
  | 				"select sheet from Sheet sheet where sheet.owner=#{user}")
  | 				.getResultList();
  | 	}
  | 
  | 	public void delete()
  | 	{
  | 		em.remove(sheet);
  | 		sheetList.remove(sheet);
  | 	}
  | 
  | 	public void select()
  | 	{
  | 	}
  | 
  | 	@Remove
  | 	@Destroy
  | 	public void destroy() {
  | 	}
  | 
  | 	public void add()
  | 	{
  | 		sheet.setOwner(user);
  | 		em.persist(sheet);
  | 		sheetList.add(sheet);
  | 	}
  | 
  | 	public void edit()
  | 	{
  | 		System.out.println("Name:" + sheet.getName());
  | 		System.out.println("Description:" + sheet.getDescription());
  | 		em.merge(sheet);
  | 		em.flush();
  | 	}
  | 
  | 	public void publish()
  | 	{
  | 		System.out.println("In the SheetManager.publish() method");
  | 	}
  | 
  | }

  | 
  | </ui:define>
  | 
  | </ui:composition>

The debug statements in the manager class's edit method show that the edited values are not being submitted from the editSheet.xhtml page.

Any ideas as to why this is not working?

Thanks in advance
