Grid: how to manage data persistence

Hi,

I want to prompt users for confirmation before persisting edited  data to the database. I am using a grid with a beanitemcontainer.
This is my structure:

Person entity class

class Person{
       Integer id;
       String name;
       @OneToMany
       Set<Addresses> addresses;

       //getters and setters
}

Addresses entity class

class Addresses{
     Integer id;
     String personAddress;
     @ManyToOne
     Person person;
     BigInteger addressOrder;
     Users lastEditedByUser;
     BigDecimal someCalculation;

     //getters and setters
}

Person View with addresses list ordered by addresses->addressOrder where addressorder is ordered by from the most prefered to the least prefered

class PersonView extends Window{
       FormLayout headerLayout; //Populated with components bound from Person bean
       Grid addressesGrid;
       BeanItemContainer<Addresses> container;

       VerticalLayout layout;

       public PersonView(Person person){
              List<Addresses> addressList=person.getAddresses().stream()
                  .sorted((a, b)->a.getAddressOrder().compareTo(b.getAddressOrder())
                  .collect(Collectors.toList());
              container=new BeanItemContainer<>(Addresses.class, addressList);
              addressesGrid=new Grid("Addresses for Person "+person.getName());
              addressesGrid.setEditable(true);
              Grid.Column addressOrderCol=addressesGrid.getColumn("addressOrder");
              addressOrder.setEditable(true);
              //other view configurations
       }
}

the problem is whenever a user edits the addressOrder, it is immediately persisted to the database even when the users closes the window without saving. is there a way i can overcome this. Utilizing the commit handler does not make sense as the window is closed without saving (committing) any data (and still any changes are persisted to the db).

​Thanks for your response
