where can i get the platform source?

[ghost]

To use facebook graph api v.2.0, some code should be modified.
For example, the class FriendTemplate is not supported 2.0

the variable FULL_PROFILE_FIELDS causes bug. user name is not supported no more. If I correct this, where could I get the original source?

the error is like this WARN : org.springframework.web.client.RestTemplate - GET request for "https://graph.facebook.com/me/friends?fields=id%2Cusername%2Cname%2Cfirst_name%2Clast_name%2Cgender%2Clocale%2Ceducation%2Cwork%2Cemail%2Cthird_party_id%2Clink%2Ctimezone%2Cupdated_time%2Cverified%2Cabout%2Cbio%2Cbirthday%2Clocation%2Chometown%2Cinterested_in%2Creligion%2Cpolitical%2Cquotes%2Crelationship_status%2Csignificant_other%2Cwebsite" resulted in 400 (Bad Request); invoking error handler {"error":{"message":"(#100) Unknown fields: username.","type":"OAuthException","code":100}}
