When creating a "manual order", i.e. an order created by an admin for another user through admin/store/orders/create, I cannot attach to the order any address information
- fill up the shipping an billing address fields manually
- select addresses in address book and have the fields filled up accordingly
- copy information form shipping to billing and vice-versa
However, when saving the order, the address data are not saved, all the fields are blanked whatever is the method for filling these data.
This fails silently, nothing in logs, no script error reported in the browser.
This is very annoying, making impossible to process an order.
I really cannot disable all modules and try one by one to find a possible conflict - more than 400 in this application. I will do my best to investigate, but at this point I don't know where to look.
Thanks for help
