Error in General Page Properties after setting Document rating via API

After setting a rating on a document via the API (TreeProvider.AddRating), viewing the General Properties tab produces an error:

Message: Exception of type 'System.Web.HttpUnhandledException' was thrown.

Exception type: System.Web.HttpUnhandledException

After searching, it looks as if the control needs to set the MaxRating property before the CurrentRating, but it is not. Would this be a bug, or are we not following the proper procedure to update a document rating?

Have you tried using the content rating webpart? Does that throw the error too? It may help to use that as a reference for your code, so you can see if you are missing something or not setting it right.

You should be able to set the rating using e.g. this way(thats how we do it internally):

float currentRating = 0.5; // has to be within 0-1 range
bool checkUserRated = true;
TreeProvider.AddRating(DocumentContext.CurrentDocument, currentRating , checkUserRated );

Richard:

We're doing that on our front-end (an MVC app), but it's when we view the document in the backend CMS that we're getting the error. This leads us to wonder if we're doing something wrong.

Does anyone know if there's a way to set the MaxRating property? The error seems to suggest that it needs set first.
