EJB3 in Action errata for EntityManager.refresh() method

[Tyronne Fernando]

The following section is from EJB 3 in Action page 299.

"An entity can become attached to the EntityManager’s context when you pass the entity to the persist, merge, or refresh method."

Does the entity get attached to the persistence context when it passed to the refresh() method or is this an error in the book?

Thanks in advance.

Which makes you to think that the entity will not get attached to the PC by the refresh() method?
And, "Tyronne Fernando", is that your real name?

The following code and text is from page 332 of EJB 3 In Action:

public Item undoItemChanges(Item item) {
entityManager.refresh(entityManager.merge(item));
return item;
}

"The merge operation is performed first in the undoItemChanges method because the refresh method only works on managed entities."

Because of this, I get the impression that the refresh() method does not attach the entity to the persistence context.

.... and Tyronne Fernando is my real name
