Hi Jan.
Thanks for your answer... That helps a lot.
So, I would like to know where should be the better place to fill the model
object with entries...
Imagine something like this:
I have some entries per day.. So, my scheduele view will be show by day
(ScheduleModel.DAY). By default, I want to fill the schedule at the first
time with data from the current day...
So, I need to get entries (in this case, from database).
On my service layer: someService.findByDay(Date day) - this method return
all messages from my database.
So, where should I call it?
I'm little bit confuse...
Thanks in advance,
Daniel
