I have a similar question like [this][1], but I couldn’t find any examples, at all, for form validation with revert option.
Suppose we have a form with **Save** and **Cancel** operations.
I want on `save()` method
the binder actually to update the bean, but on `cancel()` method, it should do nothing with the bean and leave it as it was, with previous value.

Here are my main questions:

• How the binder should be initialized, to achieve such functionality ?
• How to retrieve the updated bean on save method ?

I tried something like this, but the bean is always null on save operation

        private void initBinder() {
            binder.writeBeanAsDraft(myBean);
            binder.forField(inputField)
                    ....
        }
        
        private void save() {
            binder.writeBeanIfValid(myBean);
            binder.readBean(myBean); // retrieve the bean, to save it
            ...
            // save the bean to database
        }
        
        private void cancel() {
            binder.getBean(); // retrieve unchanged bean
            // resets the old values
            inputField.setValue(binder.getBean().getValue());
        }

Any help will great, thanks in advance!
