JavaFX tableview column switches values - mysql

Question

it's me again. so i have this javafx tableview which i have loaded dynamically with rows and columns from my database. it works out well but there's something i realized. two particular columns in the tableview switch their values. it happened once and when i cancelled the process and ran the program again, it didn't happen, then out of the blues, it happened again. i attached an image so you'd understand better. THANKS GUYS!!
below is the code that populates the tableview with Columns and rows from the database. i don't get any error when i run this.
public void buildData () {
String str = "SELECT * FROM EMPLOYEE_TABLE";
data = FXCollections.observableArrayList();
try {
ResultSet rs = DBaseUtils.dbaseExecuteQuery(str);
for(int i = 0; i < rs.getMetaData().getColumnCount(); i++) {
String columnName = rs.getMetaData().getColumnName(i + 1);
TableColumn<Employee, String> column = new TableColumn<>(columnName);
column.setCellValueFactory(new PropertyValueFactory<>(columnName));
column.setCellFactory(TextFieldTableCell.<Employee>forTableColumn());
column.setOnEditCommit(new EventHandler<>() {
#Override
public void handle(TableColumn.CellEditEvent<Employee, String> event) {
TableColumn<Employee, String> col = event.getTableColumn();
int row = event.getTablePosition().getRow();
ObservableValue<String> observe = col.getCellObservableValue(row);
if (observe instanceof WritableValue) {
((WritableValue<String>) observe).setValue(event.getNewValue());
}
}
});
empTable.getColumns().addAll(column);
}
while(rs.next()) {
Employee emp = new Employee();
emp.setEmployeeId(rs.getString(1));
emp.setFirstname(rs.getString(2));
emp.setLastname(rs.getString(3));
emp.setSex(rs.getString(4));
emp.setEmail(rs.getString(5));
emp.setPhoneNumber(rs.getString(6));
emp.setAddress(rs.getString(7));
emp.setHireDate(rs.getString(8));
emp.setState(rs.getString(9));
emp.setSalary(rs.getString(10));
emp.setDepartment(rs.getString(11));
emp.setSsn(rs.getString(12));
data.add(emp);
}
empTable.setItems(data);
empTable.setEditable(true);
} catch(Exception e) {
e.printStackTrace();
System.out.println("Error building data! ");
}
}
i also attached the model class, well... just in case.
notice the naming conventions for the Property methods, i had to use that because those were the exact names on my database. and since it PropertyValueFactory uses Reflection.
public class Employee {
private SimpleStringProperty employeeId;
private SimpleStringProperty firstname;
private SimpleStringProperty lastname;
private SimpleStringProperty sex;
private SimpleStringProperty email;
private SimpleStringProperty phoneNumber;
private SimpleStringProperty hireDate;
private SimpleStringProperty address;
private SimpleStringProperty state;
private StringProperty salary;
private SimpleStringProperty department;
private SimpleStringProperty ssn;
private long time;
public Employee() {
this.employeeId = new SimpleStringProperty();
this.firstname = new SimpleStringProperty();
this.lastname = new SimpleStringProperty();
this.sex = new SimpleStringProperty();
this.email = new SimpleStringProperty();
this.phoneNumber = new SimpleStringProperty();
this.hireDate = new SimpleStringProperty();
this.address = new SimpleStringProperty();
this.state = new SimpleStringProperty();
this.salary = new SimpleStringProperty();
this.department = new SimpleStringProperty();
this.ssn = new SimpleStringProperty();
}
public String getEmployeeId() {
return employeeId.get();
}
public void setEmployeeId(String id) {
this.employeeId.set(id);
}
public StringProperty EMPLOYEE_IDProperty() {
return employeeId;
}
public String getFirstName() {
return firstname.get();
}
public void setFirstname(String firstname) {
this.firstname.set(firstname);
}
public StringProperty FIRST_NAMEProperty() {
return firstname;
}
public String getLastName() { return lastname.get(); }
public void setLastname(String lastname) {
this.lastname.set(lastname);
}
public StringProperty LAST_NAMEProperty() {
return lastname;
}
public String getSex() {
return sex.get();
}
public void setSex(String sex) {
this.sex.set(sex);
}
public StringProperty SEXProperty() {
return sex;
}
public String getEmail() {
return email.get();
}
public void setEmail(String email) {
this.email.set(email);
}
public StringProperty EMAILProperty() {
return email;
}
public String getPhoneNumber() {
return phoneNumber.get();
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber.set(phoneNumber);
}
public StringProperty PHONE_NUMBERProperty() {
return phoneNumber;
}
public String getHireDate() {
return hireDate.get();
}
public void setHireDate(String date) {
this.hireDate.set(date);
}
public SimpleStringProperty HIRE_DATEProperty() {
return hireDate;
}
public String getAddress() {
return address.get();
}
public void setAddress(String address) {
this.address.set(address);
}
public StringProperty ADDRESSProperty() {
return address;
}
public String getState() {
return state.get();
}
Here's the image. notice the different values in the HIRE_DATE COLUMN AND ADDRESS COLUMN
