We are using the facebook like plugin with the share button. The URL points to a resource of our app. For example

http://apps.facebook.com/appname/resources/id

The first time this resource/url is shared or liked, everything works fine. The share for example holds the URL given above.

But if the same resource/url is shared again, an error occurs. Facebook did create a fanpage for that resource like

http://www.facebook.com/pages/appname

So from now on, share/likes refer to that page instead of the resource/url of our app.

The URL we use for the like plugin is correct and always points to the app resource URL. The fbappid in there is correct, too. Furthermore the page of the resource holds open graph meta tags like og:url, also pointing to the correct URL.

The facebook linter/debugger returns URLs to the correct app resource URLs, when checking the liked/shared resource.

Why is a fanpage created instead and the URL exchanged in shares/likes? How to fix it? We want the share to include the URL of the app resource and to increase the like count for that open graph object.
