DataStateBehavior causing stackoverflow

Hi,

I'm trying to use DataStateBehavior (from Blend) to control gow my MarkerSymbols behave:

Example (When setting GeoCodingDone = true on the ViewModel) i would like this pin to drop 50px and make it visible. This worked like this with Bing maps control and works immediately when i remove the DataStateBehavior. With the Behavior in place mscorlib causes stackoverflow error.

<esri:MarkerSymbol x:Key="MapPinSymbol">
         <esri:MarkerSymbol.ControlTemplate>
             <ControlTemplate>
                 <Grid ToolTipService.ToolTip="{Binding Attributes[DataContext].ServiceOrder.CustomerName}">
                        <i:Interaction.Triggers>
                            <i:EventTrigger EventName="MouseLeftButtonDown">
                                <ei:ChangePropertyAction TargetObject="{Binding DataSource, Source={StaticResource DataContextProxy}}" PropertyName="SelectedServiceOrder" Value="{Binding Attributes[DataContext].ServiceOrder}"/>
                            </i:EventTrigger>
                        </i:Interaction.Triggers>
                        <i:Interaction.Behaviors>
                            <ei:DataStateBehavior Binding="{Binding Attributes[DataContext].ServiceOrder.GeoCodingDone}" TrueState="GeoCodingDone" Value="true"/>
