* sale_product_matrix Before this commit, if we created a new row in an editable list view, do not "touched" it and clicked out of the list then the record tried to be saved and threw error notifications. Now, that flow will discard the record to make it consistent with the form view which discards the record when we leave the form. task-2431691 closes odoo/odoo#68382 Signed-off-by: Aaron Bohy (aab) <aab@odoo.com>
