Surfing on internet I found that there is a abstract class PostMixin but I don't understand how it runs.

Any suggestions?

This appears to be either an out-and-out bug or a bug caused by a change in Facebook's API. Could you please open a bug issue at https://jira.springsource.org/browse/SOCIALFB and when doing so, indicate which version of Spring Social you're using. Thanks
