[jboss-user] [JBoss Seam] - How does bijetion with new object references works?

[hubaer]

Hi all,

I have a question how bijection an object references works.

I have the following situation:
1. From a DataModel in overview page I outject an entry to details page.
2. From this page I outject the entry to a edit page.
3. Here I call a session bean via remote access and get a changed entry back.

If I assign this changed object to the variable in my action bean and outject it I get it on the next page correct. In my DataModel it is already the entry with the unchanged value.

So I seems to me that the object reference is not updated correctly.

Here a code fragment that only outject the entry but no update the data table reference:


  | @Stateful
  | @Name("userAction")
  | @Scope(ScopeType.CONVERSATION)
  | public class UserActionBean implements UserAction, Serializable {
  |  
  |     @In(required=true)
  |     @Out(required=true)
  |     private User user;
  |   
  |     public String refreshUser() {
  |     	UserManager userManager = getUserManager(); // Get the remote session bean
  |     	user = userManager.refreshUser(user);
  |     	return "userDetails";
  |     }
  | }
  | 

If I take the old entry and set the values from the changed entry I don't loose any datas.


  | @Stateful
  | @Name("userAction")
  | @Scope(ScopeType.CONVERSATION)
  | public class UserActionBean implements UserAction, Serializable {
  |  
  |     @In(required=true)
  |     @Out(required=true)
  |     private User user;
  |   
  |     public String refreshUser() {
  |     	UserManager userManager = getUserManager(); // Get the remote session bean
  |     	User tmpUser = userManager.refreshUser(user);
  |     	user.setName(tmpUser.getName());
  |     	user.setFirstName(tmpUser.getFirstName());
  |     	// ... more set actions
  |     	return "userDetails";
  |     }
  | }
  | 
    

Maybe I missing something, but I thought that the reassignment of the variable should work.
