[nhibernate-issues] [NHJIRA] Created: (NH-2404) Future queries crash (MultiQuery) when using projection queries using hql + result transformer or the linq provider (which compiles into hql)

From: Olli R. (J. <nh...@gm...> - 2010-11-01 08:53:43

Future queries crash (MultiQuery) when using projection queries using hql + result transformer or the linq provider (which compiles into hql) 
----------------------------------------------------------------------------------------------------------------------------------------------

                 Key: NH-2404
                 URL: http://216.121.112.228/browse/NH-2404
             Project:  NHibernate
          Issue Type: Bug
          Components: Core
    Affects Versions: 3.0.0.Beta2, 3.0.0.CR1
            Reporter: Olli Ryhänen
            Priority: Major


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>();

It was fixed few days ago, perhaps some weeks, fixing another issue... but I can't remember which one.
