On my recent projects we used ORC-2 as EI. Have you tried that?

this was fixed as part of #136.

did a quick test.

    var parser = new PipeParser();

    var result = parser.Parse(message);

    var ormO01 = result as NHapi.Model.V21.Message.ORM_O01;

    Assert.IsNotNull(ormO01);
    Assert.AreEqual("20060307110114", ((Base.Model.GenericPrimitive)((Base.Model.Varies)ormO01.GetORDER().ORC.PLACERORDER[0]).Data).Value);
