Sharepoint Field or property "Body" does not exist ServerException

Question

I am trying to programatically insert a discussion post into a Sharepoint discussion board list using the client object model in C#. I am using the following code:

 
var discussionList = sharepointContext.Web.Lists.GetByTitle("Discussion");

    var discussionItem = Utility.CreateNewDiscussion(sharepointContext,  discussionList, "Test");

                discussionItem["Body"           ]    = "Hello world!"
                discussionItem["Author"         ]    = 22;
                discussionItem["Editor"         ]    = 22;
                sharepointContext.Load(discussionItem);
                discussionItem.Update();
                sharepointContext.ExecuteQuery();

However, whenever I run it, I get this exception

    Microsoft.SharePoint.Client.ServerException was unhandled
      Message=Field or property "Body" does not exist.
      Source=Microsoft.SharePoint.Client.Runtime
      ServerErrorCode=-1"

Does anyone know what I'm doing wrong?

The reason the code in the question didn't work is because you called Update() after calling SPContext.Load(). If you call Update() first, you'll be fine.
