> Using HQL query to create a projection and then choosing a result transformer to it crashes when using .Future<DTO> method to turn it into a multi-query query with exception:
> System.ArgumentException: The value "System.Object[]" is not of type "DTO"  and cannot be used in this generic collection.
> The same is true when using the new .ToFuture<DTO>() support added for the linq provider and it crashes in the same location of the multi-query implementation.
> Example code that works:
> var query = session.CreateQuery("select e.Id as EntityId, e.Name as EntityName from TestEntity e")
> .SetResultTransformer(Transformers.AliasToBean(typeof (TestEntityDto)))
> .List<TestEntityDto>();
> Same query using future support causes the crash:
> var query = session.CreateQuery("select e.Id as EntityId, e.Name as EntityName from TestEntity e")
> .SetResultTransformer(Transformers.AliasToBean(typeof (TestEntityDto)))
> .Future<TestEntityDto>();
