while I accept the arguments on validation of Friedrich and see their
usefulness, just let me state two things:
- Ajax was a move away from whole form posts for good reasons. But I'm
sure you can still make every action a Form post in Aida.
- In my own application the web interface always works on a copy of
the model object which is only committed when it's in proper state
regarding the whole domain model. For example an appointment may
itself be in a valid state but may block the necessary travel time to
the next appointment in the calendar.
So for me validation is not a matter of the web interface.
Again, I'm not arguing against Friedrich's proposals on validation,
maybe you even want to scan the list archives for those validation
discussions. I just describe the way I'm doing it today.
