The javascript version of the share button shows the box_count if the user is logged into FB or not. This xfbml version only shows the box_count if the user is currently logged into Facebook so all that shows is the share logo.
This feels like a bug to me. Do I have to include yet another FB javascript in my app just to get that count?
Appreciate the work done on the implementation. If you could fix this issue it would be hugely appreciated.
