Issue when checking out child product, price = 0€? and then erase itself?

[jux]

Hello Virtuemart team and an HAppy new year 2013.

I have updated my VM 2.0.14 to 2.0.18a yesterday.
Everything work like a charm except when a customer add to their cart a product with childs product

Per exemple if they want to add this product:
http://xtremillusion.com/bague-xtrem-taille-moyenne-19mm-pistache-prodigieuse-detail

And I click on "voir le panier" the product displays correctly into the cart but the price is 0€? and when i go back it empty the cart???

I did not have this issue with VM 2.0.14

Could you please help me on how to correct this bug? its quite urgent!
Thank you

Go in the price of your child, remove the price table completly, store, then the price of the parent is taken
if you want the price to be 0.0 then you must enter 0.0

I have the same problem but it didn't get solved.

All my child prices are empty (in vm admin it also says No Price Set).

I were trying to fix it in https://forum.virtuemart.net/index.php?topic=112130.0 but still no solution

VM 2.0.18.a, no overrides, joomla 2.5.8.

  PRO told me on the other post that there have been improvements but Milbo says here that is the same... my head is a mess!
