@Unwrap onto SFSB

[tom_goring]

Hi All,

I have 2 'manager component' style beans. One called the 'Accountant' and the other 'User'. The idea is that in the session I store the id of these things and in my managers I get the real objects. Both are ScopeType.CONVERSATION. Both also use SLSB's to make the call to get the data.

The idea is that I want it to be transparent to the application code that these objects are infact reread if they have not been cached in any current conversation.

The User manager is itself a SFSB while the Accountant is a POJO (I'm trying to see the results of both methods).

Now in another SFSB (my action handler) I get some odd results using the above...

My first question is:
1) If I Inject @In(value="User", required=true) I works first time the page is displayed, but second time get get a transaction not open exception. If I change this to @In(value="User", create=true) it works ?

2) If I Inject @In(value='Accountant', create=true) I get a

6:23:48,343 WARN [Contexts] Could not destroy component: accountantCRUDBean
javax.ejb.EJBNoSuchObjectException: Could not find Stateful bean: 5c4o05-8pkcob-ezvcgh2q-1-ezvcx10a-2t

but apart from that it works ?

Here is my code:

@Stateful
@Name(UserComponentNames.User)
@Scope(ScopeType.CONVERSATION)
public class UserComponentManagerBean implements UserComponentManager {

 @In(value=UserComponentNames.UserId,required=false)
 private Long userId = null;

 @EJB
 private UserManagerLocal userManager;

 @Logger private Log log;

 private User cachedUser=null;

 @Create
 public void create() {
 log.info("create");
 }

 @Unwrap
 public User getUserComponent() {
 if ( cachedUser!=null ) {
 return cachedUser;
 }
 if ( userId!=null ) {
 cachedUser = userManager.getUser(userId);
 return cachedUser;
 }
 return null;
 }

 @Destroy @Remove
 public void destroy() {
 log.info("destroy");
 }
}

@Name(AccountantComponentNames.Accountant)
@Scope(ScopeType.CONVERSATION)
public class AccountantComponentManager {

 @In(value=AccountantComponentNames.AccountantId,required=false)
 private Long accountantId = null;

 @In(create=true)
 private CompanyManagerLocal companyManagerLocal;

 private Accountant cachedAccountant=null;

 @Unwrap
 public Accountant getAccountantComponent() {
 if ( cachedAccountant!=null ) {
 return cachedAccountant;
 }
 if ( accountantId!=null ) {
 cachedAccountant = companyManagerLocal.getAccountant(accountantId);
 return cachedAccountant;
 }
 return null;
 }
}

@Stateful
@Scope(ScopeType.CONVERSATION)
@Name("accountantCRUDBean")
public class AccountantCRUDBean extends StandardCRUDBean<Accountant> implements AccountantCRUD, Serializable {
 private static final long serialVersionUID = 1L;

 @In(value=AccountantComponentNames.Accountant, create=true)
 private Accountant userLinkedAccountant=null;

 @In(value=UserComponentNames.User, create=true)
 private User user;

 @EJB
 private CompanyManagerLocal companyManager=null;
