如果勾选或取消勾选复选框，我需要您在启用和禁用基于rowSelectCheckbox和rowUnselectCheckbox的inputText时的帮助。如果勾选了，那么我需要启用inputText，否则应该在页面加载和取消时禁用它。默认情况下，在页面加载时禁用inputText。这是jsf的代码：

private List<Student> employeeList = new ArrayList<Student>();
private List<Student> selectedEmployees;
private boolean disable;

@PostConstruct
public void init() {
    //add Employees
    disable=true;
    Student w1 = new Student(111, "AAAA", "ZZZZ", "", disable);
    Student w2 = new Student(222, "CCCCC", "ZZZZZ", "OUT", disable);
    Student w3 = new Student(222, "BBBBBB", "YYYYYYY", "IN", disable);

    employeeList.add(w1);
    employeeList.add(w2);
    employeeList.add(w3);

}

public void EnableInputText(SelectEvent event) {


    for(int i=0;i<=selectedEmployees.size();i++){ //Assuming you have declared as List
        for(int j=0;j<=employeeList.size();j++){          
        if(selectedEmployees.get(i).getId().equals(employeeList.get(j).getId()))
        {
           employeeList.get(j).setDisable(false);
             break;
        }
       }
     }
}

以下是bean中的代码：

public class Student {
    private Integer id;
    private String name;
    private String location;
        private String remarks;
        private boolean disable;

    public Student(Integer id, String name, String location, String remarks, boolean disable){
                    this.id = id;
                    this.name = name;
                    this.location = location;
                    this.remarks=remarks;
                    this.disable=disable;
            }

    public void setId(Integer id) {
        this.id = id;
    }

    public Integer getId() {
        return id;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setLocation(String location) {
        this.location = location;
    }

    public String getLocation() {
        return location;
    }

    public void setRemarks(String remarks) {
        this.remarks = remarks;
    }

    public String getRemarks() {
        return remarks;
    }

    public void setDisable(boolean disable) {
        this.disable = disable;
    }

    public boolean isDisable() {
        return disable;
    }

在Bean中，如果勾选了行，我在启用inputText时遇到困难。你能帮忙吗？现在我收到了错误： java.lang.IndexOutOfBoundsException：Index：3，Size：3 if if tick and checkbox

首先使用selectionMode="multiple"，这意味着接下来将启用textField的多行而不是这个：

 <h:inputText value="#{emp.remarks}" disabled="#{empBean.enable}" />

写

 <h:inputText value="#{emp.remarks}" disabled="#{emp.enable}" />

表示在bean之后声明一个变量enable：

    for(int i=0;i<=selectedEmployees.size();i++){ //Assuming you have declared as List
     for(int j=0;j<=empList.size();j++){          
     if(selectedEmployees.get(i).getId().equals(empList.get(j).getId()){
        empList.get(j).setEnable(false);
     }
    }
  }

在此之前，您可以编写一个for loop并停用所有textField列表，以便rowUnselect
