[Dolibarr-dev] How can this condition be true ?

[Philippe GRAND]

Hi all

within function 
pdf_getlinedesc($object,$i,$outputlangs,$hideref=0,$hidedesc=0,$issupplierline=0)

I wonder how I can get this condition true :

if ($issupplierline)
    {
        include_once 
DOL_DOCUMENT_ROOT.'/fourn/class/fournisseur.product.class.php';
        $prodser = new ProductFournisseur($db);
    }

.....

Regards
