I also have a stateful page view that displays a list of xxxx as a @DataModel.
I also have conversations external to the page that manipulate entries int he
model.
I call back from the conversations... and manipulate the mode.
In my code that requires to manipulate the model Inject it.
| /**
| * Biject the Find Users Controller which has to refine its list of
Users
| * When we update the Users then we have to laise with the
FindUsersController to refine its list of users.
| */
| @In(create=true)
| private FindUserController findUserController;
|
then call back to it
| @End
| @TransactionAttribute(TransactionAttributeType.REQUIRED)
| public String create() {
| log.info("> create");
| user.getDates().setCreationDate(new Date());
| user.setPassword(encryptionController.encrypt(user.getPassword()));
| em.persist(user);
| em.flush();
| facesMessages.addFromResourceBundle(FacesMessage.SEVERITY_INFO,
"user_create_successful");
|
| /*
| * We need to add this user to the list of users in the session
scoped FindUserController
| */
| if (findUserController != null) {
| findUserController.addUserToExistingList(user);
| }
|
| log.info("< create");
| return "success";
| }
|

In my model, it doesn't have to re-read anything from the database.
I found this useful as I had problems managing to get my stateful model to
"re-read" from the database as it only kept reading from the cache! and I
didn't know how to invalidate the cache.
It did save any reads from the database.
However, I am sure Gavins way is better.
