Entity Lifecycle

Consider the following table:

CREATE TABLE validation(
  validation_id NUMBER PRIMARY KEY,
  string_column_nn VARCHAR2(50) NOT NULL,
  string_column_n VARCHAR2(50) NULL,
  number_column_nn NUMBER NOT NULL,
  number_column_n NUMBER NULL
);

INSERT INTO validation VALUES (1, 'STRING', NULL, 1, NULL );
INSERT INTO validation VALUES (2, 'STRING', NULL, 2, NULL );

COMMIT;

So, observation is that if we call any setter from doDML, then the entity is re validated, whereas if we just update an attribute then framework automatically post those values in doDML method and validateEntity() is not called again for that row.
