      GB2 v. 1.4.0, Sakai 2.6.x - In some gradebooks users consistently get an error when they try to update a student's score for an item. The error says:
      Failed Request
      Failure to update grade for [student's name]. Unexpected response from server: 500.
      (see screenshot)

      The truth is it does actually update the grade in the db. It just doesn't reflect it in the client. Following the error message, if a user refreshes the gb2 tool and comes back, the update did save. This leads me to believe it's a timeout thing where the client isn't receiving a confirmation "handshake" from the server in time, so it assumes it failed.

      This is very repeatable in one particular gradebook but I've heard reports of it happening intermittently elsewhere. In the trouble-gradebook, there are no categories. There are some externally maintained items from Samigo but other than that everything looks very standard. Class size of 16 with 19 items. The error message occurs using IE, Firefox, and Chrome.
