Very sorry for not getting back to this sooner. I missed the post somewhere along the lines. Let's see if we can get you going.
For the Object, you want to set it up as an "Article" or a blog post, or whatever you want your EasyBlog posts to be called. If you use an object that Facebook has already defined, like "article", that would be a "built-in FB Object". If you create your own object type, then it's not built-in to Facebook.
As for the action, you'll want to create your own action type, like "Comment". That way, a user can 'Comment' on an 'Article'.
Once those are created in the Facebook Developers area, you need to create them in the Open Graph area of JFBConnect. Make sure you have the Open Graph - EasyBlog plugin enabled. Then, create your object:
Name: Blog Posts
Type: article
Built-in: Yes
On the right side, select the category this object is for
Next, create your action:
Name: Comment
Type: comment
Built-in: No
Associate this action with the Object you created above.
On the right, set the trigger type to "Manual"
That should be what you need to do. Whenever our plugin detects a comment associated with an EasyBlog post/object, it should automatically post that to the user's Timeline.
Hope that helps, but if you have issues with the above, let us know.
Thanks,
Alex
