If no data was sent then wouldn't the routing fail ?
Maybe I should have looked more closely but seemed to me that the problem was exactly what the exception stated : there is no parameterless constructor for the model....
>No parameterless constructor would indicate nothing is being sent from jquery. Put in some Alert boxes to test for specific values.
