The objects passed in appear to be valid and the entity object has the [serializable] attribute on it.

OK, stupid me. I wrapped the call in a try catch and this is the error
Type 'BTSystems.PantryWare.Business.ABusinessEntity' in Assembly 'BTSystems.PantryWare.Business, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

What is needed for the class to be Serializable other than the attribute?
