issue with wrapper variable

Question

Apex Controller:

 public with sharing class FirstWrapperClass {

    public string w { get; set; }

   //----------Datatypes--------------
   public list<FirstWrapperExample>wrp {get;set;}
   list<FirstWrapperExample> wrp_old = new list<FirstWrapperExample>();
   //------------------DefaultConstructor------------
    Public FirstWrapperClass(){
          wrp = new list<FirstWrapperExample>();
          wrp = getAccounts_in_wrp();
      wrp_old = new list<FirstWrapperExample>();
      wrp_old = getAccounts_in_wrp();
    }

    public list<FirstWrapperExample> getAccounts_in_wrp()
     {
      list<FirstWrapperExample> tempwrp = new list<FirstWrapperExample>();

      list<Account> tempaccountlist = new list<Account>([Select id,name,type,active__c,
       (select id,name,Address_line_2__c,country__c,Landmark__c,pin__c,state__c from Address__r where primary__c=true)from Account
        where Active__c='yes']);
        for(Account accobj:tempaccountlist)
        {
           //create the address instance
           Address__c addrss = new Address__c();
            for(address__c addrssobj : accobj.address__r)
                      addrss = addrssobj;
                      if(accobj.address__r.size()>0)
                      {
                       tempwrp.add(new FirstWrapperExample(accobj,addrss));
                      }
        }
        return tempwrp;
     }
     //----------WrapperClass------------
    Public class FirstWrapperExample{
      public Account account{get;set;}
      public Address__c Add {get;set;}
     //---------------Wrapper Parameterized Constructor---------------------

Error:

Error: Unknown property 'String.account'

Answer 1

You have a public String property named w declared in the apex class which is not used in the class but conflicting with the apex:repeat loop variable which is also named w.

So either change the loop variable name to something else, or remove the property w defined in the class.
