Abstract
Model calculations of the pion from factor are performed in light-front dyn amics. Valence and nonvalence contributions are obtained. It is shown that the nonvalence parts can be very large and may dominate even at moderate an d large values of the momentum transfer. The consequences for the interpret ation of noncovariant calculations are discussed.
