Unify.Framework.Collections.GroupedNameValueCollectionMissingFieldException: The method IEntityBase`.GetValue() is not supported in this context.  Use IEntityBase`.GetValueOrDefault() instead.

The method is not supported as use of this method in a LINQ statement against an implementation will result in the same exception type being thrown if the key value is not present in an instance of the entity.
