QueryBatch and AliasToBean - giving a no persister error.

[sianmace]

I am trying to execute a stored procedure - that returns a table and a count
I found some code online that showed how to exploit the QueryBatch to get these two results at the same time.

If i map the "Report" result as a domain object, the below code (without the AliasToBean) works fine.
However, I didnt want to do this as the results do not have a primary key, so i wanted to just map them to a DTO as shown below.

This errors with MappingException: No persister for: Report

Is this possible?
am i missing something?
is this a bug?

IQuery query = CurrentSession
                .CreateSQLQuery($"EXEC sp_Report")
                .AddEntity(typeof(Report).FullName)
                .SetResultTransformer(Transformers.AliasToBean(typeof(Report)));


 IQueryBatch queries = CurrentSession.CreateQueryBatch()
                .Add<Report>(query)
                .Add<int>(CurrentSession.CreateSQLQuery(" ").AddScalar("Total", NHibernateUtil.Int32));

  IList<Report> results = queries.GetResult<Report>(0);
            int totalRecordCount = queries.GetResult<int>(1).Single();

OK, I think i was being dumb.
Just omit the AddEntity part!
