Infinite or NaN values in finalRect

  Hi,
  I have strange error at categorized line chart with one point. I will try to narrow down and find the cause of it later this day. But I think it will be interesting for you to see error details.

Message: Unhandled Error in Silverlight Application

Category: ManagedRuntimeError       
Message: System.InvalidOperationException: UIElement.Arrange(finalRect) cannot be called with Infinite or NaN values in finalRect.

Update:

My bad, this bug should be in Beta forum. I could reproduce this bug on Q2 assemblies. And got everything working on Q1.
So this is bug of Q2.
Here is code to reproduce my bug. When line chart has on point it throws exception. When I add second point with new category. Works just fine.

P.S.: Please move this post to Beta forum.

Thanks, Alexey

ObservableCollection<DataSeries> dataSeries = new ObservableCollection<DataSeries>();
DataSeries series = new DataSeries();
series.Definition = new LineSeriesDefinition();
series.LegendLabel = "Legend Label";
DataPoint dataPoint = new DataPoint
                        {
                            YValue = 10,
                            XCategory = "Category 01"
                        };
series.Add(dataPoint);
//dataPoint = new DataPoint
//              {
//                YValue = 20,
//                XCategory = "Category 02"
//              };
series.Add(dataPoint);
dataSeries.Add(series);
SeriesMappingCollection seriesMappings = new SeriesMappingCollection();
for (int serieIndex = 0; serieIndex < dataSeries.Count; serieIndex++)
{
    DataSeries chartSeries = dataSeries[serieIndex];
    SeriesMapping seriesMapping = new SeriesMapping();
    seriesMapping.CollectionIndex = serieIndex;
    seriesMapping.LegendLabel = chartSeries.LegendLabel;
    seriesMapping.SeriesDefinition = chartSeries.Definition;
    seriesMapping.ItemMappings.Add(new ItemMapping(DataPointMember.YValue.ToString(), DataPointMember.YValue));
    seriesMapping.ItemMappings.Add(new ItemMapping(DataPointMember.XCategory.ToString(), DataPointMember.XCategory));
    seriesMappings.Add(seriesMapping);
}
testChart.SeriesMappings = seriesMappings;
testChart.ItemsSource = dataSeries;

Hi Alexey Oyun,

We are aware there is a problem when having a single point Line series in our Q2.Beta release. Our developers have already resolved this issue and you can expect the fix available in our official Q2 2010 release, expected later this week.

Please, accept our apologies for the inconvenience caused.

Is this issue resolved? I just downloaded the latest internal build of 7.30 but issue was still present
