Question

I am trying to post a Action to the Facebook Timeline using the JS API

FB.api('/me/application:action_type' + '?opject_type='+document.location.href,'post',
      function(response) {
          if (!response || response.error) {
              alert("error");
          } else {
              alert("success");
          }
      });

Posting works quite well and the API returns no error. A new activity appears at the Timeline but only as a small text within the “recent activities” box which looks like this:

What could be the problem if the action is not displayed like in the Attachment Preview of the Action Type Settings? Which look like this:

I have linked all the properties from the Object Type and tested my Object URL with the Facebook Debugging Tool and it looks like all the attributes can be parsed correctly by the Facebook scraper.

I also defined a aggregation layout for the action type. So what can be the reason that no Attachment is displayed?

Answer 1

I also reported this issue as a bug to facebook. Their reply was that this behavior is by design and the attachment layout only appears in the activity log or when multiple activities have been posted to a users timeline.
