Hi guyz,
      Here is the solution for the issue we had

public class ListTextActionForm extends ActionForm {
   public List customer;

   public void setCustomer(List customer){
           this.customer = customer;
   }

   public List getCustomer() {
           return this.customer;
   }

   public void reset(ActionMapping mapping,HttpServletRequest request) {
           int count=0;
           String id ="";
        if (null!=this.customer) {
            System.out.println("List size1 :"+this.customer.size());
            int numRows = this.customer.size();
            while (null!=request.getParameter("customer["+ numRows +"].id"))
{
                    id = request.getParameter("customer["+numRows+"].id");
                    this.customer.add(new Customer(id,request.getParameter
("customer["+numRows+"].firstName"),request.getParameter
("customer["+numRows+"].lastName"),request.getParameter
("customer["+numRows+"].address"));
);
                    numRows++;
            }

          } else {
               System.out.println("List is Empty");
           }
   }
}

Put the new added row in to the ActioForm collection to create bean for the
added row.
Thanks
Irfan
