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

["Kevin Haskett" <KHaskett@xxxxxxxxxxx>]

Yes, I have tried marking it as Transient.. Yes it is possible this
field was set in a previous session.  Can you point me to the place
where I could get some more info on the descriptor merge event you refer
to?  Are there code examples for this?

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.
