BubbleSeriesDefinition supports a property called "Visibility".

I can set it in XAML to a hard coded value:

    
                                    <chart:BubbleSeriesDefinition BubbleSizeRelative="False" 
        
                                                                  Visibility="Visible" 
        
                                                                  ItemStyle="{StaticResource RadEventBubble}"></chart:BubbleSeriesDefinition> 
        
                                </chart:SeriesMapping.SeriesDefinition>

But when I try setting it to a databound value, Silverlight has a fatal error and the application does not load (it is gettting a XAML parse error on the line with the binding to the Converter:

 
                                                                  Visibility="{Binding EventDisplay, Converter={StaticResource Bool2Visible}, Mode=OneWay}" 
        
                                                                  ItemStyle="{StaticResource RadEventBubble}"></chart:BubbleSeriesDefinition> 
        
                                </chart:SeriesMapping.SeriesDefinition>

The probably is NOT in the converter, since I use that same converter in othe examples, and it returns the value Visibility.Collapsed or Visibility.Visible depending on the boolean value.

I am enclosing the converter, and you can see that it is providing the correct type (SeriesVisibility):

    
            using System; 
        
            using System.Windows; 
        
            using System.Windows.Data; 
        
            using Telerik.Windows.Controls.Charting; 
        
            namespace BloodHound2

                /// <summary>

                public class Bool2SeriesVisible : IValueConverter

                        else 
        
                        { 
        
                            return SeriesVisibility.Collapsed; 
        
                        }

                    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
        
                    { 
        
                        throw new NotImplementedException();
