Changes to CoreResultsWebPart fetched properties not saving

  Hi,

  I am trying to configure several aspects of the default search webparts in an enterprise search center through a feature receiver.  I'm starting with the fetched properties of the search results.  I found this other post about how to access the fetched properties of the core results webpart through code, so I'm trying to use that property (SelectedColumns) to make the changes I want.  However, my changes don't stick.  I'm also setting UseLocationVisualization to false, and after activating the feature if I go in and edit the webpart, I can see that it has been unchecked, so I know I'm hitting the right webpart, but the fetched properties stay as the default list of columns.  Here's my code:

                  SPFile resultsPage = (SPFile)web.GetFileOrFolderObject(web.Url + "/Pages/results.aspx");
                  resultsPage.CheckOut();
                  resultsPage.Update();
                  wpManager = web.GetLimitedWebPartManager(resultsPage.Url, PersonalizationScope.Shared);
  
                  CoreResultsWebPart coreResults = null;
                  foreach (System.Web.UI.WebControls.WebParts.WebPart webPart in wpManager.WebParts)
                  {
                      if (webPart.GetType().Equals(typeof(CoreResultsWebPart)))
                      {
                          coreResults = (CoreResultsWebPart)wpManager.WebParts[wpManager.WebParts.IndexOf(webPart)];
                          coreResults.UseLocationVisualization = false;
                          coreResults.SelectColumns = @"<Columns><Column Name=""WorkId""/> <Column Name=""BlahBlahBlah""/></Columns>";
                          wpManager.SaveChanges(coreResults);
                      }
                  }
  
                  resultsPage.CheckIn(string.Empty);
                  resultsPage.Publish(string.Empty);
                  resultsPage.Update();

  
  

  Does anyone know what I might be missing in order to get my SelectColumns value to stick?

  Thanks,

  Dylan
