Explicitly parse XFBML

[tomfrit]

Hello, I haven't had any luck with your module and figured it is because you need to explictly parse the generated XFBML after the view updates. Adding a parse method to your provider with FB.XFBML.parse(); and calling it on stateChangeSuccess (using UI Router) seems to do the trick.
