我需要一个带有 RadioCheckbox 的 DataTable 然后找到了链接
FacesException:启用选择时,DataModel 必须实现 org.primefaces.model.SelectableDataModel
所有我需要的,但是在运行页面时是空白的并且没有给出异常。
无论如何,我也会发布我的代码。

豆:
@ManagedBean
@SessionScoped
public class TableBean implements Serializable{
private static final long serialVersionUID = 1L;
private List<Car> cars;
private Car car;
private CarDataModel carsModel;
public TableBean() {
cars = new ArrayList<Car>();
Car car1 = new Car();
car1.setModel("BMW");
car1.setRandomColor("Black");
cars.add(car1);
Car car2 = new Car();
car2.setModel("Audi");
car2.setRandomColor("White");
cars.add(car2);
carsModel = new CarDataModel(cars);
}
public List<Car> getCars() {
return cars;
}
public String onRowSelect(){
System.out.println("Row Click!!!");
return "otherpage";//Does this nav works???if not how???
}
public Car getCar() {
return car;
}
public CarDataModel getCarsModel() {
return carsModel;
}
public void setCarsModel(CarDataModel carsModel) {
this.carsModel = carsModel;
}
汽车数据模型:
public class CarDataModel extends ListDataModel<Car> implements SelectableDataModel<Car>, Serializable {
private static final long serialVersionUID = 1L;
public CarDataModel(List<Car> data) {
super(data);
}
@Override
public Car getRowData(String rowKey) {
@SuppressWarnings("unchecked")
List<Car> cars = (List<Car>) getWrappedData();
for(Car car : cars) {
if(car.getModel().equals(rowKey))
return car;
}
return null;
}
@Override
public Object getRowKey(Car car) {
return car.getModel();
}
我不知道可以是什么。
谢谢!
