Ektorp ArrayList get all in JSF in the PrimeFaces List component

How can i get my List of existing Tourneys via Ektorp API from CouchDB? My code looks like this:

thanks a lot.

I call the methode getAll() in my TourneyService Class and getAll() is a list of Tourneys

//TourneyService

@Service
public class TourneyService implements Serializable{

private static final long serialVersionUID = 699617628013084160L;

@Autowired
private TourneyRepository tourneyRepository;

public List<Tourney> getAllTourneys(){
    return tourneyRepository.getAll();
}
}

//TourneyRepository

@Component
public class TourneyRepository extends CouchDbRepositorySupport<Tourney> {

@Autowired
public TourneyRepository(@Qualifier("cegocouchdb") CouchDbConnector db) {
    super(Tourney.class, db);
    initStandardDesignDocument();
}

@GenerateView @Override
public List<Tourney> getAll() {
    ViewQuery q = createQuery("all")
                    .descending(true)
                    .includeDocs(true);
    return db.queryView(q, Tourney.class);
}

   }

//TourneyListBean

    @ManagedBean(name = "TourneyListMmgtBean")
    @RequestScoped
    public class TourneyListBean implements Serializable {

private static final long serialVersionUID = 6130842812974474768L;

@ManagedProperty(value = "#{tourneyService}")
private TourneyService tourneyService;

private List<Tourney> tourneys; 

public void onEdit(RowEditEvent event) {
    FacesMessage msg = new FacesMessage("Tourney changed", "");

    FacesContext.getCurrentInstance().addMessage(null, msg);
}

public void onCancel(RowEditEvent event) {
    FacesMessage msg = new FacesMessage("Aktion abgebrochen", "");

    FacesContext.getCurrentInstance().addMessage(null, msg);
}


public TourneyService getTourneyService() {
    return tourneyService;
}

public void setTourneyService(TourneyService tourneyService) {
    this.tourneyService = tourneyService;
}

public List<Tourney> getTourneys() {
    tourneys = tourneyService.getAllTourneys();
    if (tourneys == null) {
        tourneys = new ArrayList<Tourney>();
    }
    return tourneys;
}

public void setTourneys(List<Tourney> torneys) {
    this.tourneys = torneys;
}
   }

Error:

org.ektorp.support.ViewGenerationException: Cannot generate 'all' view for null.

@GenerateView has the following constraints:

• The method must be named findBy[Property]. If a @TypeDiscriminator is defined, the "all" view used by the getAll method can also be generated.
• The method may only have one parameter.
• The property must exist in the target class.

Verify that you have an @TypeDiscriminator in your Tourney class
