When a visitor places several orders in a row and Ecommerce logging is activated, the Ecommerce log only shows the cart details (items of the order), that were sent with the first order.
All following orders of the visitor only show the order total and item count in the Ecommerce log widget (but not the item names and single prices etc.)
Attachment: Screenshot of Ecommerce log; 2nd and 3rd order do not show item details though those were submitted to Piwik too.
(In ) Fixes #2736
Thanks for the report!
