EntityManager.refresh() - Works on Detatched Or Managed Enti

[P-298 Of EJB3 In Action Book] States: In the diagram, it shows that using a refresh method a detatched entity can become managed..
[P-332Of EJB3 In Action Book] States: The refresh method only works on managed entities...
Aren;t the above 2 statements contradictory? Moreover Statement1 is incorrect...

1. Re: EntityManager.refresh() - Works on Detatched Or Managed

Hi,

the second statement is correct. To make a detached entity managed, you have to use "find" or "getReference".

See https://www.hibernate.org/hib_docs/ejb3-api/javax/persistence/EntityManager.html#refresh%28java.lang.Object%29

Best regards
