Re: Re[eclipselink-users] fresh entity throws java.lang.IllegalArgumentException
|
If you found the object in the same EntityManager then it should still be
managed, and refresh should work.
Ensure you are not calling clear(), also if in JEE ensure the object was
found in the same transaction, as in a managed EntityManager each
transaction represents a new persistence context.
Otherwise you could be somehow changing the object's primary key, ensure the
primary key is the same. You could try doing a find before the refresh to
see what the registered object is.
