Finding problem in setting a value for h:selectBooleanCheckbox

[Balaji Natarajan]

Hi
i have just started J S F few days before and i am now stuck in a problem and the definition is given below.
Problem: I have a check box named "Select All" and a list of Check Boxes (generated using a data table). When you click "Select All" all check boxes in data table should be clicked automatically. This i have achieved through "valueChangeListner" and its working fine. But the real problem comes, when i uncheck any of the check box inside datatable, "Select All" check box should be unchecked.

Following is the JSP

<h:selectBooleanCheckbox id="checkAll" value="#{listBean.allSelected}" immediate="true" onklick="submit()" valueChangeListener="#{listBean.checkBoxClicked}"/>
<h:outputText id="selectAll" value="Select All"/>
<h:dataTable id="customers" value="#{listBean.customers}" var="customer">
<h:column id="custname">
<br>
<h:selectBooleanCheckbox id="checkCustomer" value="#{customer.customerSelected}" immediate="true" onklick="submit()" valueChangeListener="#{listBean.checkBoxClicked}"/>
<h:outputText id="selectCustomer" value="#{customer.name}"/>
</h:column>
</h:dataTable>

Following is my backing bean

public class ListBean {
private boolean allSelected;

private ListBeanDelegate delegate = new ListBeanDelegate();

private List customers = new ArrayList();

{
System.out.println("Setting customers");
setCustomers(delegate.getCustomers());
}
 
public List getCustomers() {
return customers;
}
 
public void setCustomers(List customers) {
this.customers = customers;
}
 
public boolean getAllSelected() {
return allSelected;
}
 
public void setAllSelected(boolean isAllSelected) {
this.allSelected = isAllSelected;
}

public void checkBoxClicked(ValueChangeEvent event) {
        FacesContext context = FacesContext.getCurrentInstance();
    String value = event.getNewValue().toString();    
    String id = event.getComponent().getClientId(context);
   
    System.out.println("Value:"+value);
    System.out.println("ID:"+id);    
    
    String [] tokens = id.split(":");
    int tokenLength = tokens.length;
    if(tokenLength==2){
    System.out.println("Select All is clicked");    
    List tempList = getCustomers();
    List tempCustList = new ArrayList();
    for(int index=0;index<tempList.size();index++){
    Customer c = (Customer)tempList.get(index);
    
    Customer c1 = new Customer(c.getName(),c.getCustomerSelected());
    if(value.equals("true")){
    System.out.println("Checking Customer");
    c1.setCustomerSelected(true);
    }
    else{
    System.out.println("UnChecking Customer");
    c1.setCustomerSelected(false);
    }    
    tempCustList.add(c1);
    }
    setCustomers(tempCustList);
    }
    else if(tokenLength==4){
    System.out.println("Customer is clicked");
    int custIndex = Integer.parseInt(tokens[2]);
    List tempList = getCustomers();
    List tempCustList = new ArrayList();
Customer c = (Customer)tempList.get(custIndex);

Customer c1 = new Customer(c.getName(),c.getCustomerSelected());
if(value.equals("true")){
System.out.println("Checking Customer");
c1.setCustomerSelected(true);
}
else{
System.out.println("UnChecking Customer");
c1.setCustomerSelected(false);
[B]this.setAllSelected(false);[/B]

System.out.println("AllSelected:"+getAllSelected());
}
tempList.remove(custIndex);
tempList.add(custIndex,c1);
    setCustomers(tempList);
    }    
        context.renderResponse();
    }
}

i have set the managed bean in session scope.

please help me!!!

this.setAllSelected(false); given in valueChangeListener sets the managed bean boolean member as false. this is bound to the Select All check box in jsp. Why is this not getting reflected?

please help!!!
