RE: [eclipselink-users] ObjectChangeSet old value
|
Hi Tim,
> Mathias, I believe this was brought up on the mailing list before see:
> http://dev.eclipse.org/mhonarc/lists/eclipselink-users/msg00544.html
I saw this posted. But in my situation, I don't have access to the old
properties anymore (because the entity is stored in a conversion scope of my
webapp and any html form changes are performed transparently by the web
framework). That's why I used getUnitOfWorkChangeSet.
EclipseLink must know the previous values to compute the object change set.
Now I want to know how I can access these previous values or the old entity
object.
Neither em.merge(entity) nor uow.getOriginalVersionOfObject() return the old
object.
BTW: In your posted solution, the ObjectChangeSet does not return the old
value too.
Even if I can get the old object, I don't know how to access the attributes
listed in ObjectChangeSet.getChangedAttributeNames(). How did you do that?
Did you use the reflection API?

Kind regards,
Mathias
