error in cart plugins after migration from vm2.6 to vm3.0.2

[motybz]

I try to adjust the plugin to the new system but some functions have changed or do not exist.
There is a doc detailing the changes between vm2.6 to vm3 in the shopping cart functions?
like this "Fatal error: Call to undefined method VirtueMartCart::prepareCartViewData() in C:\xampp\htdocs\joomla3\plugins\system\vponepagecheckout\cart\cartview.html.php on line 1118"

Hi Hutson,

I have same problem, i did search and readed links you gave, but it useless for me
I can't find solution to replace prepareCartViewData function. Can you explain more for me? or someone can help me?

if (!class_exists('VirtueMartCart')) require(JPATH_VM_SITE . DS . 'helpers' . DS . 'cart.php');
$cart = VirtueMartCart::getCart();
and
$cart->prepareCartViewData(); // this is error line

Thank so much !

surely it is simpler to get the VM3 version of vponepagecheckout?
