Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1 on updating of an entity via hibernate - spring

Question

When trying to update an entity from the controller, I keep getting this exception. Rest assured, thorough research regarding this exception has been made, but none of the suggestions have worked in my case.
I am trying to update the doctor entity by calling hibernate session.update(entity);
Doctor model:
#Entity
#Table(name = "tbl_doctor")
public class Doctor {
private Long id;
private PersonInfo personInfo;
private String licenseNumber;
private User user;
private String specialization;
private String employmentStatus;
private String suffix;
private List<Patient> patients;
//
// #OneToMany
// #JoinTable(name = "Doctor_Appointment", joinColumns = { #JoinColumn(name
// = "doctor_id") }, inverseJoinColumns = { #JoinColumn(name = //
// "appointment_id") })
// private List<Appointment> appointments;
public Doctor() {
super();
user = new User();
personInfo = new PersonInfo();
}
#Override
public String toString() {
String patients= "";
for(Patient p: this.patients) {
patients += p.toString();
}
return "Doctor [id=" + id + ", personInfo=" + personInfo
+ ", licenseNumber=" + licenseNumber + ", user=" + user
+ ", specialization=" + specialization + ", employmentStatus="
+ employmentStatus + ", suffix=" + suffix + ", patients="
+ patients + "]";
}
#Column(name = "fld_license_number")
public String getLicenseNumber() {
return licenseNumber;
}
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "key_user")
public User getUser() {
return user;
}
#Column(name = "fld_specialization")
public String getSpecialization() {
return specialization;
}
#Column(name = "fld_employment_status")
public String getEmploymentStatus() {
return employmentStatus;
}
#Column(name = "fld_suffix")
public String getSuffix() {
return suffix;
}
#OneToMany(cascade = CascadeType.ALL)
#JoinColumn(name = "key_patient")
#Fetch(value = FetchMode.SUBSELECT)
public List<Patient> getPatients() {
return patients;
}
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "key_doctor")
public Long getId() {
return id;
}
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "key_person_info")
public PersonInfo getPersonInfo() {
return personInfo;
}
//setters
}
Person info just includes the biodata like first name, last name, sex, birthday etc.
Controller
#RequestMapping(value="/update_doctor.it", method=RequestMethod.POST)
public String updateDoctor(HttpSession session, #ModelAttribute("doctor") Doctor doctor, Model model, #RequestParam("id") long adminId) {
System.err.println("update doctor controller");
String username = session.getAttribute("user").toString();
session.setAttribute("user", username);
doctor.getUser().setEnabled(true);
doctor.getPersonInfo().setDateModified(LocalDate.now());
doctorDao.updateDoctor(doctor);
return "redirect:/view_doctor_profile.it?id=" + doctor.getId();
}
DaoImpl
#Override
public void updateDoctor(Doctor doctor) {
Session session = sessionFactory.getCurrentSession();
session.update(doctor);
}

Answer 1

I figured it out. A lot of classes or entities are dependent on the doctor, the entity I'm updating. In order for the batch update to execute successfully, I had to place a on the jsp, fetching all the ids of the dependent classes. Thank you!
