It's not a good idea to use awakeFromInsertion because it's called everytime you insert an object into an editingContext.
I suggest you to use validateForSave and validateForInsert:


public void validateForInsert() throws NSValidation.ValidationException {
setCreationDate(new NSTimestamp());


    super. validateForInsert();
}

public void validateForSave() throws NSValidation.ValidationException {
    setModificationDate(new NSTimestamp());

    super. validateForSave();
}

Hi there,

I need to add tracking fields to my database that
track when a record was last updated and when a record
was added.  I believe I can use the awakeFromInsertion
method on EOCustomObject (in the superclass for all my
EOs) to set the time the record was added but I'm a
little confused how I set the date last modified time
automatically?  Or, is this something I need to set on
the EO before I save changes?  Thanks...
