Hi Greg,
the thing about ModelDriven is that the model object gets pushed on the
value stack _before_ your action method is executed. To initialize the
model object before the ModelDrivenInterceptor comes into play, just
implement Preparable and do your initialization in prepare() (as Lukasz
already suggested)
