How to enable/disable inputText on rowSelectCheckbox

[maas]

I need your help in enabling and disabling inputText based on rowSelectCheckbox and rowUnselectCheckbox if the checkbox is ticked or unticked. If it is ticked, then I need to enable the inputText otherwise it should be disabled on page load and on untick. By default the inputText is disabled on the page load. Here is the code for the jsf:

Code: Select all

 <h:form id="request">
            <p:dataTable value="#{dataTableView.employeeList}" id="Employee" var="emp"
                         selection="#{dataTableView.selectedEmployees}" rowKey="#{emp.id}">
            <p:ajax event="rowSelectCheckbox" listener="#{dataTableView.EnableInputText}" />
        <p:ajax event="rowUnselectCheckbox" listener="#{dataTableView.EnableInputText}" />

    <p:columnGroup type="header">
        <p:row>
           <p:column/>
           <p:column headerText="ID"/>
           <p:column headerText="Name"/>
           <p:column headerText="Location"/>
           <p:column headerText="Remarks"/>
        </p:row>
    </p:columnGroup>
        <p:column selectionMode="multiple" style="width:2%;text-align:center"/>
                <p:column headerText="ID">
                    <h:outputText value="#{emp.id}"/>
                </p:column>
                <p:column headerText="Name">
                    <h:outputText value="#{emp.name}"/>
                </p:column>
                <p:column headerText="Location">
                    <h:outputText value="#{emp.location}"/>
                </p:column>
                <p:column headerText="Remarks">
                    <h:inputText id="inputT1" value="#{emp.remarks}" disabled="#{emp.disable}"/>
                </p:column>
            </p:dataTable>
        </h:form>

And in the backing bean:

Code: Select all

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);
        }
       }
     }
}

I am facing difficulties in enabling the inputText for entry if the row is ticked. So could you please help. Now I got the error : java.lang.IndexOutOfBoundsException: Index: 3, Size: 3 if I tick the checkbox

Its a basic java question.You are trying to access index3 which doesn't exist.It should be i<size but not i<=size.
