Getting IllegalStateException: No data type for node:...
I successfully got the seam registration example running. I took that example, changed a few classes so I could begin getting familiar with seam, but I can not get past this one exception:

I mirrored the registration example almost exactly, here are the relevant files:
@Entity
@Name("car")
@Scope(SESSION)
@Table(name="cars")
public class Car implements Serializable
{
private static final long serialVersionUID = 1881413500711441951L;
private String vin;
private String make;
private String model;
private Integer year;
public Car(String vin, String make, String model, Integer year) {
this.vin = vin;
this.make = make;
this.model = model;
this.year = year;
}
public Car() {}
@Id @NotNull
public String getVin() {
return vin;
}
public void setVin(String vin) {
this.vin = vin;
}
public void setName(String vin) {
this.vin = vin;
}
@NotNull
public String getMake() {
return make;
}
public void setMake(String make) {
this.make = make;
}
@NotNull
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
@NotNull
public Integer getYear() {
return year;
}
public void setYear(Integer year) {
this.year = year;
}
public String toString()
{
return "Car(VIN: " + vin + " Make: " + make + " Model: " + model + " Year: " + year + ")";
}
}
@Stateless
@Name("sellcar")
public class SellCarAction implements SellCar
{
@In @Valid
private Car car;
@PersistenceContext
private EntityManager em;
@Logger
private Log log;
public String sell() {
List existing = em.createQuery("select car from Car where vin=:vin")
.setParameter("vin", car.getVin())
.getResultList();
if (existing.size()==0) {
em.persist(car);
log.info("Sold car with vin #{car.vin}");
return "/sold.jsp";
}
else {
FacesMessages.instance().add("Car vin: #{car.vin} has already been sold");
return null;
}
}
}
@Local
public interface SellCar {
public String sell();
}

Hibernate claims to be generating all of the schema, and there are no additional errors to report. Any help would be greatly appreciated.
Thanks.
