Cannot add Pricebook2Id to an Order when creating a new Order

Reference: http://salesforce.stackexchange.com/questions/101218/php-soap-client-cannot-set-price-book-to-an-order

When I tried to create a first OrderItem for the Order, it said that I need to assign a price book for the order I created (what I did before but no succeed).

The error message returned from the server: "Order: bad field names on insert/update call: Pricebook2Id"

Have you solved the problem? EDIT: I solved the problem by updating the WSDL file to the newest version.

@matejbasic I think I did the same thing like you said and it worked! Thanks for replying.
