具有panelGrid的bean的实例

Question

我使用panelGrid来显示我的结果，但是我有一个问题，我不知道我的类在panelGrid中的实例如何，我的列表有问题，我无法添加元素，我有错误，我认为我需要实例我的班级，但我不知道如何，如何在列表中添加元素？

这是我的代码：

@Component("points")
public class Points extends FormTemplate implements Serializable {

    private String taskId;
    private TaskInfo currentTask;
    private int taskNumber;
    Map<String,Object> varsMap;
    private ArrayList<RhReunionEntretin> pointsObjects;
    private ArrayList<RhReunionEntretin> removedPoints;
    private String loggedUser;



    @Override
    public void init() {

        if(varValues.get("points") != null)
            pointsObjects= (ArrayList<RhReunionEntretin>)varValues.get("points");
        else
            pointsObjects   = new ArrayList<RhReunionEntretin>();
        if(pointsObjects.size() == 0){
            List<Long> pointsMultiline = new ArrayList<Long>();
            if(varValues.get("form_1475754639065") != null) {
                pointsMultiline = (List<Long>) varValues.get("form_1475754639065");
                if (pointsMultiline != null && pointsMultiline.size() != 0) {
                    for (Long pr : pointsMultiline) {
                        RhReunionEntretin point = (RhReunionEntretin) businessService.getEntitytById("com.imaginepartners.imagineworkflow.models.rh.RhReunionEntretin", pr.toString());
                        pointsObjects.add(point);
                    }
                }
            }
        }
        removedPoints   = new ArrayList<RhReunionEntretin>();

        loggedUser      = userService.getLoggedInUser().getId();
    }

    public void addPoint() {
        pointsObjects.add(new RhReunionEntretin());
    }
