Number of comments with SocialCommentManager.GetComments

Question

In my custom webpart, I want to show the number of comments. I try to get this throug SocialCommentManager.GetComments and then return comments.Count.

The problem is: I get only comments for the current user. Say, there are three comments on a page, one is mine. On startpage in a custom webpart I see that there is only one comment.

Even if I run with elevated, the users get only the number of their comments.

int number;
SocialComment[] comments = null;
SPSecurity.RunWithElevatedPrivileges(delegate
     {
         using (SPSite esite = new SPSite(SPContext.Current.Site.ID))
         {
             var sc = SPServiceContext.GetContext(esite);
             var soc = new SocialCommentManager(sc);
             comments = soc.GetComments(uri, maxNumberOfComments);
             number = comments.Count();
         }
});

While logged in as System Account, I get all (System Account is set as the administrator on User Profile Service).

Any ideas?

I found a solution: You must renew the HttpContext.

int number;
SocialComment[] comments = null;    
SPSecurity.RunWithElevatedPrivileges(delegate
         {
             using (SPSite esite = new SPSite(SPContext.Current.Site.ID))
             {
                 var ctx = HttpContext.Current;
                 try
                 {
                     Log.Info("Trying to get comments");                                                             
                     var sc = SPServiceContext.GetContext(esite);
                     HttpContext.Current = null;
                     var soc = new SocialCommentManager(sc);
                     comments = soc.GetComments(uri, maxNumberOfComments);
                     number = comments.Count();
                 }
                 catch (Exception ex)
                 {
                     Log.Error(ex);
                 }
                 finally
                 {
                     HttpContext.Current = ctx;
                 }            
             }
    });

You can use the override with the Uri.
