Hi jipock,
 
Assuming that the entity type you are looking for is Employee, the Property is LastName, and you are validating only new entities:
 
protected override bool ValidateSave() {
  var em = EntityManager;
  var foundEntities = em.FindEntities(typeof(Employee), EntityState.Added);
 
  foreach (Employee entity in foundEntities.Cast<Object>().ToList()) {
  if (entity.LastName == null) {
    em.RemoveEntity(entity);
  }
  return base.ValidateSave();
}
 
Note that, back in the client, while the successfully saved entities were updated to EntityState.Unchanged, the "unsaved" entities still have EntityState.Added.
 
Silvio.

Good Afternoon,
 
I'm attempting now to validate an entity upon save that is Property1 on a specific entity type is null then stop the save and throw an exception.
 
I'm not finding a good way to do this... I thought to look into the EntityServerSaveInterceptor, but ValidateSave() doesn't take parameters, nor do I find a way of grabbing the entities being saved (and manually loop through all of them). The entity itself does have PropertyInterceptors for individual properties (before Set, After Set, etc.), but I don't want to check it until Save time.
 
Any suggestions on this?
