Re: [eclipselink-users] Question on initial "field values"

[James Sutherland <jamesssss@xxxxxxxxx>]

Have you marked the fields as @Transient?

For the existing object, were these fields set previously?  They may still
have the existing values from the persistence context, or shared cache.  If
you do not want them cached you can clear them using a descriptor merge
event, or instantiation copy policy.
