New Post: Missing property type

Hi,

Fairly new to composite and C#.
After I've updated my Global Datatype, the page that shows a form using Formrenderer doesn't work anymore.

'Composite.Data.GeneratedTypes.Reservations_TripReservationsEmptyClass' does not contain property 'TripDescription'

How or where can I regenerate the above class?
The property type is indeed the new field I've added, but I don't have an idea how or when this is generated.
