EntityManagerDelegate

Marcel,

I want to update a related entity on saving.

This is the code (just after the assign of then

          var entity = args.Entities.OfType<Booking>()
                      .FirstOrDefault(e => e.EntityAspect.EntityState.IsAddedOrModified());

          if (entity != null)
            UpdateBookingReminders(entity, args);
        }


        private void UpdateBookingReminders(Booking booking, EntitySavingEventArgs args)
        {
          var payments = booking.BookingPayments;
          BookingPayment payment;

          foreach (var reminder in booking.BookingReminders)
          {
            if (reminder.Milestone == "DEPARTURE")
            {
              var due = booking.departure.AddDays(reminder.offset);
              reminder.SetValue("Due", due);                          
              args.Entities.Add(reminder);
              reminder.EntityAspect.SetModified();
            }

But is doesn't seem to update anything. What am i doing wrong.

BTW i am using cocktail 1.0

Not sure at the moment what's going on. Try these. Instead of calling SetValue, why don't you just assign the due data? reminder.Due = due. That should already set the entity to modified, so then you can skip the call to SetModified. Set a breakpoint and make sure the Due data was actually changed and that the entity is in modified state.

Sorry guys, it was my code that failed.

I did set my value (which was wat i saw in de debugger), but i overlooked the rest of my code.

But it is good to know where to put my code.
