[TYPO3-commerce] hook delivery prices

[Bas van der Togt]

Hello,

I'm trying to build an extension to calculate the delivery cost based on 
which country is selected in pi2. I build a hook for this, see the 
attached code. The problem is that i can't get this code working as 
hook. it's only working when i put the code in the function getListing 
in class.tx_commerce_pi3.php

My second problem is that when i finish the order the price of the 
delivery product is set back to default.

My third problem is that there's no delivery product added to the list. 
The price of the delivery product is calculated but you can't see for 
which product.

Hopefully somebody can help me to solve these 3 problems.

kind regards,
Bas
