DataStateBehavior causing stackoverflow

[PetteriLehtonen]

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">
