public class BinderValidationStatus<BEAN> extends Object implements Serializable

Binder validation status change. Represents the outcome of binder level validation. Has information about the validation results for the field level and binder level validation.

Note: if there are any field level validation errors, the bean level validation is not run.

Note: if the status change is triggered via automatic validation due to a changed field value, the field validation statuses will only cover the changed fields.

Use Binder.setValidationStatusHandler(BinderValidationStatusHandler) to handle form level validation status changes.
