Answer 1

The best comprehensive solution in four steps is:

1) add a file Product.php to \override\classes containing:

 ObjectModel::TYPE_INT, 'validate' => 'isUnsignedInt');
class Product extends ProductCore 
{ 
   public $mystock; 
} 

2) open adminFolder/themes/default/template/controllers/products/informations.tpl and place your field with the correct name and id in the appropriate place.

3) delete file cache/class_index.php

4) add your field to the DB, for number field:

ALTER TABLE ps_product ADD mystock INT NOT NULL;
