Editor Binding Error

BenTreptow1

I'm getting a null reference exception on my Editor. The Layers property in my Map is databound to my view model and removing this property from the Map seems to eliminate the error, so I'm thinking the Editor control won't work with a Map that has databound layers. Is this true? Does anybody know of a workaround for this?

Here's the error:

System.NullReferenceException

You cannot put Map control under Resources. According to this MSDN Documentation: all objects under resources must be "shareable" http://msdn.microsoft.com/en-us/library/cc903952%28v=vs.95%29.aspx
