I am trying to implement the patern shown in the "Live Data" sample for XamPivotGrid.
The sample does not show how to re-wire the DataSource.ResultChanged event after it has completed.
When I try to rewire the event the grid crashes.  Please see the attached demo project.

void DataSource_ResultChanged(object sender, AsyncCompletedEventArgs e)
        {
            PeopleGrid.DataSource.ResultChanged -= DataSource_ResultChanged;
            BackgroundWorker worker = new BackgroundWorker();
            worker.DoWork += new DoWorkEventHandler((a, b) =>  this.Dispatcher.Invoke(new Action(() => FilterData())));
           
            // Attempting to re-wire the ResultChanged event causes a crash:
            worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler((c, d) => PeopleGrid.DataSource.ResultChanged += new EventHandler<AsyncCompletedEventArgs>(DataSource_ResultChanged));
            worker.RunWorkerAsync();
        }

Thank you,
Sam

As I was posting this request I noticed this post: http://community.infragistics.com/forums/t/69409.aspx
I downloaded the code and ran it (changing the references to version 11.2) but I get null reference
exceptions.  Perhaps there is a bug in 11.2?
