When trying to implement WCF dataservices using NHibernate I had a blocking error.

the call to 
http://localhost:32774/NorthWindNHibernateDataService.svc/Orders(4)/OrderLines
generated the following Linq query
db.Orders.Where(element => element.OrderId == 4).SelectMany(element => (IEnumerable<OrderLine>)element.OrderLines)
//{value(NHibernate.Linq.NhQueryable`1[OrderLines]).Where(element => (element.OrderId == 4)).SelectMany(element => Convert(element.OrderLines))}

which throws a QuerySyntaxException
