[Rob Blair]

the graph explorer shows this post that returns json that causes a NPE in Post.getLikeCount().

Since it has no likes node, the ReferenceListAndCountDeserializer will return null, making calls that use like throw NPE.
This is, as they say, a problem.
Added comments at https://jira.springsource.org/browse/SOCIALFB-41
Will have to work around it locally for the time.

I'll look into it, but before I do...can you confirm that you're using the latest snapshot builds when seeing this?

just did a git pull, saw updates to a bunch of docs stuff, but no code changes.

Merge pull request #33 from habuma/master

Updated README to reflect new build process

and comparing to what I have checked in (using SVN for our local source control, merging vendor to our branch)

TwistyWindyPassage:spring-social-facebook robblair$ svn status
? build

Alright, then I'll have a look. Sounds like a bug to me. Will queue it up on my todo list and let you know.

Quick update: I just pushed a fix for this into the latest 1.1.0.BUILD-SNAPSHOT build. If no likes information is available, the getLikes() and getLikeCount() methods will return null.
