If an object is detached then you call makePersistent. If an object is
not persistent (i.e transient) then you call makePersistent. If an
object is attached then you don't call anything. Can't get simpler.

Demonstration of such would be nice, with a definition of what is the
expectation ("properly") based on the testcase.

I'm sure it would be nice to know what is "not working properly".
Reference to a testcase and the log would be desirable also, since the
log tells you what is being detached and when, according to the fetch
plan. We have a large number of testcases for JDO and JPA that
demonstrate detaching from the persistence context and all are working
fine; the same code is used to run the JDO and JPA TCKs.
