Unable to cast object of type 'MongoDB.Bson.BsonObjectId' to type 'MongoDB.Bson.BsonBoolean' Serializer Error

[Victor Bautista]

Hi,

I am getting this error from the MongoDB serializer in .net:

Unable to cast object of type 'MongoDB.Bson.BsonObjectId' to type 'MongoDB.Bson.BsonBoolean'

As I am a newbie I am not sure where this is coming from, it does not happen inside the controller or the view. Following is a portion of the stack trace:

[InvalidCastException: Unable to cast object of type 'MongoDB.Bson.BsonObjectId' to type 'MongoDB.Bson.BsonBoolean'.]
   MongoDB.Bson.BsonValue.get_AsBoolean() in c:\projects\mongo-csharp-driver\Bson\ObjectModel\BsonValue.cs:77

Does anybody else have this problem?
