nHibernate result from multiple SQL queries is empty

Question

I'm grouping several SQL queries in a single multiquery. The queries are successfully executed. The result of multiQuery.List() is an ArrayList of ArrayLists. So far so good. However, the individual ArrayLists contain values of type {object[0]} or, if I use a result transformer, properties with their value set to null. I won't list the entire set of SQL queries here but this is what my multi query looks like:

        var multiQuery = Session.CreateMultiQuery()
            .Add<IList<DTO1>>("query1", query1)
            .Add<IList<DTO2>>("query2", query2)
            .Add(..)
            .Add(..);
        var results = multiQuery.List();

Pretty standard in my eyes, but it doesn't work unfortunately. I'm using the latest version of Fluent nHibernate (1.2). This version comes with nHibernate 3.1 by default, which doesn't support SQL queries inside a multi query.

To get this working, I added nHibernate 3.2 to my project and added the following to my web.config.

        <dependentAssembly>
            <assemblyIdentity name="NHibernate"
                              publicKeyToken="aa95f207798dfdb4"
                              culture="neutral" />
            <bindingRedirect oldVersion="3.1.0.4000"
                             newVersion="3.2.0.4000"/>
        </dependentAssembly>
