Retrieveing data when using api 2.7

[mlarizzate]

Hi guys!
I'm having some problems with lots of methods.

When i want to get a post, comment, conversationMessage or photo objects y need to send the list of all parameters I need from all these objects.

Example for Post:

String[] fields = new String[]{"created_time", "type,id", "from", "message", "to", "story", "updated_time", "object_id", "properties", "place", "message_tags", "picture"};
PagedList<Post> posts = facebookTemplate.pageOperations().facebookOperations(pageId).fetchConnections(pageId, "feed", Post.class, postParametersMap, fields);

Example for conversartionMessages:

fields = new String[]{"id", "created_time", "tags", "from", "to", "message", "attachments"};
        PagedList<ConversationMessage> conversationsMessages = facebookTemplate.pageOperations().facebookOperations(pageId).fetchConnections(conversationId, "messages", ConversationMessage.class, params, fields);

Example for coments:

String[] fields = {"created_time", "id", "attachment", "from", "message", "comment_count", "parent", "object"};
        Comment comment = facebookTemplate.pageOperations().facebookOperations(pageId).fetchObject(objId, Comment.class, fields);

I think this is the right way to do it, but when i need to get a Photo:
Photo photo = facebookTemplate.mediaOperations().getPhoto(postId);
My Photo object comes only with Id and Created_time parameters.

if I use an app with api 2.3 it does not happen, all the attributes are present.
I think you miss to add the availability to add a fields array in come methods
is this a bug or i'm doing something wrong?
