Boa tarde pessoal.
Estou tentando implementar o DataTable Row Editing do showcase do primefaces, porém quando vou executar aparece o seguinte erro:

[/code]Meu MB está assim(igual do showcase):
@ManagedBean(name="tableBean")
@SessionScoped
public class TableBean implements Serializable {
private final static String[] colors;
private final static String[] manufacturers;
private List<Car> carsSmall;
static {
colors = new String[10];
colors[0] = "Black";
colors[1] = "White";
colors[2] = "Green";
colors[3] = "Red";
colors[4] = "Blue";
colors[5] = "Orange";
colors[6] = "Silver";
colors[7] = "Yellow";
colors[8] = "Brown";
colors[9] = "Maroon";
manufacturers = new String[10];
manufacturers[0] = "Mercedes";
manufacturers[1] = "BMW";
manufacturers[2] = "Volvo";
manufacturers[3] = "Audi";
manufacturers[4] = "Renault";
manufacturers[5] = "Opel";
manufacturers[6] = "Volkswagen";
manufacturers[7] = "Chrysler";
manufacturers[8] = "Ferrari";
manufacturers[9] = "Ford";
}
public TableBean() {
carsSmall = new ArrayList<Car>();
populateRandomCars(carsSmall, 9);
}
private void populateRandomCars(List<Car> list, int size) {
for(int i = 0 ; i < size ; i++)
list.add(new Car(getRandomModel(), getRandomYear(), getRandomManufacturer(), getRandomColor()));
}
public List<Car> getCarsSmall() {
return carsSmall;
}
private int getRandomYear() {
return (int) (Math.random() * 50 + 1960);
}
private String getRandomColor() {
return colors[(int) (Math.random() * 10)];
}
private String getRandomManufacturer() {
return manufacturers[(int) (Math.random() * 10)];
}
private String getRandomModel() {
return UUID.randomUUID().toString().substring(0, 8);
}
public String[] getManufacturers() {
return manufacturers;
}
public String[] getColors() {
return colors;
}
public void onEdit(RowEditEvent event) {
FacesMessage msg = new FacesMessage("Car Edited", ((Car) event.getObject()).getModel());
FacesContext.getCurrentInstance().addMessage(null, msg);
}
public void onCancel(RowEditEvent event) {
FacesMessage msg = new FacesMessage("Car Cancelled", ((Car) event.getObject()).getModel());
FacesContext.getCurrentInstance().addMessage(null, msg);
}
}
Vi que caso eu retire o bloco <p:cellEditor> e deixe apenas a chamada do get #{car.model} ele abre a página (mais não edita claro).
Estou utilizando o JSF: javax.faces-2.2.1.jar
E primefaces: primefaces-4.0.jar
Obrigado.
