Failed to post as a Page #163

Using spring-social-facebook-2.0.1.RELEASE.jar

When trying to post as a Page admin I get the following error:

(#100) Tried accessing nonexisting field (accounts) on node type (Page)

My code is:

            String accessToken = ... ; // the page access token
            String pageId = ...; // the page id 
            Facebook facebook = new FacebookTemplate(accessToken);
            PageOperations pageOperations = facebook.pageOperations();
            PagePostData pagePostData = new PagePostData(pageId);
            pagePostData.link("http://www.mysite.com/mypage", null, null, null, null);
            pageOperations.post(pagePostData);

The stack trace is:

My take:

the library is trying to get the account details using a page token, which is not a permitted operation. I guess it should skip this step, which is needed when posting as the user (with a user access token), if the access token is a PAGE access token.

I did some research on this and looks like spring social facebook operations are meant to be user token centric.
