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

I have tried adding code to the postMerge event, but this seems like it
is too late in the process.  Is there an event that would fire when the
record was initially read?

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.
