I’ve noticed that for Configurable products at least the product name displayed in the ‘Order Review’ section of the one-page checkout is different from the product name displayed in the Cart/Basket page.
It appears to not show the configurable item title but I didn’t investigate too much. It seemed strange that the names and other product details displayed in these two locations we not called from the same bit of code. Could someone from the Magento team read and confirm if this is indeed an oversight?
The solution is to replace app\design\frontend\OC\default\template\checkout\onepage\review\info.phtml with the attached file.
