    Does anyone know if it's possible to track changes of the individual
    properties of a data object?
    I know there is the get persistence state but it's for the whole object.
    I'm trying to do some custom validations in a validateForUpdate method
    and allow only certain fields to be modified.
    Just wondering.

    Thanks,

    Fredrik
