i dont think its the same,
i think is an incompatibility between
custom_grocery_crud
and the new version of grocery crud so maybe
custom_grocery_crud
have to be fixed.
I will report it here so maybe someone can help
To use it - drop the subclass into the application/libraries folder
right beside grocery_crud.php
call the new file custom_grocery_crud.php
Edit application/controllers/examples.php
class Examples extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->database();
$this->load->helper('url');
//$this->load->library('grocery_Crud');
$this->load->library('custom_grocery_crud');
}
...
function offices_management()
{
try{
//$crud = new grocery_CRUD();
$crud = new custom_grocery_crud();
$crud->set_theme('datatables');
$crud->set_table('offices');
$crud->set_subject('Office');
$crud->required_fields('city');
$crud->columns('city','country','phone','addressLine1','postalCode');
//our demo
$crud->field_set_defaults('city' , 'readonly', 'Hobart,Tasmania');
$output = $crud->render();
$this->_example_output($output);
}catch(Exception $e){
show_error($e->getMessage().' --- '.$e->getTraceAsString());
}
}
use field_set_defaults exactly the same way you would use field_type
Here's the subclass 
custom_grocery_crud.php
and here it is inline for you to peruse:
