I have the following Problem:
When i restore an old shopping cart with an article that has been deleted all the fields are replaced with 'default' parameters and the price is set to 0.
I have seen that the suppliers give back a string without Parameters (all is empty) and then the parameters are replaced with default values. Is this behaviour correct and i have to adapt the behaviour of the Shopping cart or should the supplier not send back a string with 'empty' values?
