Call to undefined method App\Models\[...]::transStart

My model function is given bellow:

PHP Code:

class Product extends Model
{

    protected $table            = 'products';
    protected $primaryKey      = 'product_ID';
    protected $returnType      = 'object';
    protected $useSoftDeletes  = false;
    protected $allowedFields    = ['....'];


    public function saveProduct( $new ){
        $val = [];
        if( $new ){
            $val['product_AID']    = AID;
            $val['product_GPID']    = $this->GPID();
            $val['product_by']      = session('user41BApp'.AID);
        }else{
            $info['updated']        = time();
        }

        $val['product_title']  = esc($this->request->getPost('pName'));
        $val['product_slug']    = planeText(esc($this->request->getPost('pName')));
        $val['product_price']  = esc($this->request->getPost('pPrice'));
        $val['product_data']    = json_encode($data);
        $val['product_info']    = json_encode($info);

        $this->transStart();
        $this->save($val);
        $this->saveCat();
        $this->transComplete();

        return ($this->transStatus() === FALSE) ? FALSE : [$val['product_GPID'], $this->request->getPost('cat')];

    }
} 


There is a strange problem.

PHP Code:

model->saveProduct(true); // This is working fine 


PHP Code:

model->saveProduct(false); // This is not working. Showing error:
//Call to undefined method App\Models\Product::transStart

1) Have you tested without this method? (commenting it)

2) It may seem obvious, is this method well implemented ? the code doesn't show it, with the closing class brace.

PHP Code:

$this->db->transStart();
$this->save($val);
$this->saveCat();
$this->db->transComplete();

Thank you for your response.
1. Without transection, both method are doing as expected.

Code:

model->saveProduct(true); // Saving product
model->saveProduct(false); // Updating product

With transection only the update product "model->saveProduct(false);" showing the error.

2. This method is a part of a large class. Everything is doing well except the update method.

I am not using Query Builder. Using inherited Codeigniter model instead. Again those method are not working just for

PHP Code:

model->saveProduct(false);

PHP Code:

$info['updated']        = time(); 


Why is this line using the variable $info and not $val (like the rest) ?

PHP Code:

$info['updated']        = time(); 


Why is this line using the variable $info and not $val (like the rest) ?

This is using in the last line where assigning the value:

PHP Code:

$val['product_info']    = json_encode($info);

I would check the model code, because an update requires that an id field be passed to it.
