Hello. I create Win8 App with Wikipedia API. Created REST Service get Response in xml. In test tab it works well. It get all needed params and I can Automatically Create Service Response. After I map it to UI and invoke service on button click event. But when I test App in browser in console I have:
Mozilla: XML Parsing Error: no element found Location: moz-nullprincipal
Chrome: XMLHttpRequest cannot load http://en.wikipedia.org/w/api.php?sea.... Origin http://project.tiggzi.com is not allowed by Access-Control-Allow-Origin.
Using Tiggzi Proxy did not help.
What is the problem?

Hello! Could you send us service URL, service settings and request parameters so we can test it. Screenshots would also help
