[PJUG Javamail] How do you Update DETACHED Value object ?

[Umesh Gohil]

                    Hi All,





I am trying to update detached object. Some fields value changed to
null in value object by user. Now those fields whose value changed to
null is totally ignored by JPA . 




Solution to this problem is I am creating temp Value Object by setting
primary key and calling super.get on temp value object in transaction
and then set all the fields of new VO object then only those fields
value will be changed in database.





Few thing I have to take care of like 


1> Concurreny Exception


2> Some fields value is set by framework like createdt, updatedt, createUserid, updateUserId





Please suggest best alternative
