Result lazyloaded but whole tree being selected

[Anderson Fortaleza]

Hi, I have the following ResultMap:

    <resultMap id="rmSerie" class="Serie">
      <result property="SerieID" column="SerieID"/>
      <result property="Descricao" column="Descricao"/>
      <result property="Abreviacao" column="Abreviacao"/>
      <result property="Sigla" column="Sigla"/>
      <result property="Curso" column="CursoID" select="qryCursoPorID" 
lazyLoad="true"/>
      <result property="TurnoIntegral" column="TurnoIntegral"/>
    </resultMap>

And the following statement:

    <select id="qrySeriePorEmpresaID" resultMap="rmSerie" parameterClass="int">
      <![CDATA[
        SELECT DISTINCT Serie.SerieID, Serie.Descricao, Serie.Abreviacao, 
Serie.Sigla, Serie.CursoID, Serie.TurnoIntegral
        FROM V_Serie Serie
         JOIN V_Curso Curso ON (Serie.CursoID = Curso.CursoID)
         JOIN V_Empresa Empresa ON (Curso.EmpresaID = Empresa.EmpresaID)
         JOIN V_Turma Turma ON (Turma.SerieID = Serie.SerieID)
         JOIN V_PeriodoLetivo PeriodoLetivo ON (Turma.PeriodoLetivoID = 
PeriodoLetivo.PeriodoLetivoID)
        WHERE Empresa.EmpresaID = #EmpresaID#
          AND Curso.TipoCurso = 'N'
          AND Ano = YEAR(GETDATE())
          AND TurnoIntegral = 0
        ORDER BY Serie.Sigla
      ]]>  
    </select>

I call the select statement in my code:

IList<Serie> SerieEmpresa = 
Mapper.Instance().QueryForList<Serie>("qrySeriePorEmpresaID", 
ddlSede.SelectedItem.Value);
ddlSerie.DataSource = SerieEmpresa;
ddlSerie.DataBind();

I'm checking the queries requested in my SQL Server with Profiler and the 
select "qryCursoPorID" lazyloaded on the result is executed (N + 1 problem is 
taking place), despite the lazyload attribute. I don't use any Curso property 
or anything, actually checking the SerieEmpresa object right after the filling 
of that object brings me the whole object tree.

Lazyloaded is being completly ignored. I'm using DataMapper 1.5.1. Am I doing 
something wrong or fogetting something ?
