Facebook Graph API post message with link to page's wall - facebook

Question

My problem is: When I post to page's wall some message with link it shows as Posted By Others, without link it shows normally in page timeline (Im group's admin ).
The same code posts to my timeline just fine:
I use AS3 library.
My permissions:
"publish_stream", "user_photos","publish_actions","manage_pages"
my post code:
var params:Object = new Object();
params.message = messageTextInput.text;
params.description = "description";
params.caption = "caption";
params.name = "name";
params.link = "http://www.ya.ru";
params.picture = "http://image.bayimg.com/cajchaado.jpg";
FacebookDesktop.api(page.id+"/feed", onCallApi, params, "POST"); //use POST to send data (as per Facebook documentation)
Facebook documentation says I can post either link or message, but it works just fine, except of showing in "Recent posts by others" ( please see attached screenshot ).

To post on a fanpage on behalf of itself (not the user), you have to use the page access token.
What happening is- when you make the call, the sdk uses the default token (user token), so the post is published on behalf of the user which is displayed in the "Recent Post by Others" section in the page.
Since you have requested for manage_pages already in your code, you can simply obtain the page access token with this call- /{page-id}?fields=access_token. Use this token with your current call just by adding the parameter access_token-
....
params.picture = "http://image.bayimg.com/cajchaado.jpg";
params.access_token = "{page-access-token}";
....
