Spring Social Web - Activity object without content when Accessing with OAuth2

[luisfmp]

Hi everyone.

I'm trying to use spring-social-google to search activities in google+, but when i get the activity objects they came with the Content property set to null. Is this a permission problem?

I use OAuth2 to get the permissions. The code is like this:

OAuth2Operations oauthOperations = googleConnectionFactory.getOAuthOperations();
    OAuth2Parameters params = new OAuth2Parameters();
    params.setRedirectUri(applicationUrl + GOOGLE_REDIRECT_URI);
    params.setScope("https://www.googleapis.com/auth/plus.me https://www.google.com/m8/feeds/ https://www.googleapis.com/auth/userinfo.email  https://www.googleapis.com/auth/userinfo.profile");
    params.set("access_type", "offline");
    params.set("approval_prompt","force");
    
    String authorizeUrl = oauthOperations.buildAuthorizeUrl( GrantType.AUTHORIZATION_CODE, params );

I get the Access token and Refresh token with no problem, then i made the search with:

		List<Publication> activities = new ArrayList<Publication>();
		ActivityQueryBuilder searchResult = google.activityOperations().activityQuery();
		searchResult.searchFor(query);
		ActivitiesPage page = searchResult.getPage();
		List<? extends Activity> activityList = page.getItems();
		activities.addAll( (List<Publication>) CollectionUtils.collect( activityList, new ActivityToPublicationTransformer() ) );

The transformer contains this transform method:

public Object transform(Object input) {
		Publication publication = null;
		if (input instanceof Activity){
			User user = new User();
			Activity activity = (Activity) input;
			publication = new Publication();
			publication.setPublicationId(activity.getId());
			publication.setType( PublicationType.ACTIVITY );
			publication.setSocialNetwork( SocialNetwork.GOOGLE );
			user.setName(activity.getActor().getDisplayName());
			user.setUserId(activity.getActor().getId());
			publication.setUser(user);
			publication.setMessage(activity.getContent());
			publication.setCreatedTime(activity.getPublished());
			publication.setShares(activity.getResharers());
			publication.setComments(activity.getReplies());
			publication.setAttentions( new ArrayList<Attention>() );
		}
		return publication;
	}

When I debug the application, the instrucction "activity.getContent()" in the transformer returns me null, but activity.getPublished() or activity.getId() works fine.

Any hint about what am i doing wrong?

Is there any page with the JavaDoc of spring-social-google? I searched it but i didn't find it

P.D. Sorry mi bad english, it's not my natural language.
P.D.2 I just realized I wrote wrong the title, it should begin with "Spring Social Google" not "Spring Social Web", could an admin change the title?
