Hello all. I've just provided a sample use case and files for that at http://bit.ly/cx_shop_and_payment_1 . As described in http://bit.ly/cx_shop_and_payment_usecase_1 , it is simple netstop-and-payment senario. I hope it will help for understanding CX. Wish your happy new year anyway and have a good time with your familiy. ------ hdknr.com
