unable to show Checboxes from wrapper.

I am unable to checkboxes from a wrapper class to visualforce page. I am getting unknown property error everytime.


Here is the Visual Force Page



<apex:page controller="chkBox">
 <apex:form >
<apex:pageBlock >
  <apex:pageBlockTable value="{!getVal}" var="p" >
  <apex:repeat value="{!}" var="a">
    <apex:column >
    <apex:inputCheckbox value="{!a}"/>
   <apex:pageBlockButtons > <apex:commandButton action="{!save}" value="Save"/></apex:pageBlockButtons>

 The Controller


public class chkBox {
list<wrapbox>  wrp= new list<wrapbox>();
    public PageReference save() {
    String test = ApexPages.currentPage().getParameters().get('test');
        return null;

    public  list<wrapbox> getGetVal() {
    wrapbox mywrp = new wrapbox();
    for(integer i =0;i <10; i++){
    mywrp = new wrapbox();
    for(integer j =0;j <10; j++){;
        return wrp;




The Wrapper Class:



public class wrapBox{
public List<Boolean> box{get;set;} 
public wrapBox(){
box = new List<Boolean>();
public class wrapBox{public List<Boolean> box{get;set;} 
public wrapBox(){box = new List<Boolean>();}}


Please suggest how to show the Boolean list from wrapper class to the visual force. I am expecting a table of checkboxes.
