algorithmic modeling for Rhino

Hi everyone,

im trying to build a component in VS that excepts a list of point3d. hence the following

      protected override void RegisterInputParams(GH_Component.GH_InputParamManager pManager)
        {

            pManager.AddPointParameter("Line Points", "LPT", "This is a test Line.", GH_ParamAccess.list);

        }

to which in the solving routine I try to copy this into a variable like so

  protected override void SolveInstance(IGH_DataAccess DA)
        {

            RhinoList<Point3d> holderPts = new RhinoList<Point3d>();

            if(!DA.GetDataList(1 , holderPts)) {return; }

}

but this gives me the following error. "the type arguments... cannot be inferred from the usage. try specifying the type arguments explicitly..."

why inst this working?

im basically trying to do this the same way that the "list component" example from the SDK does it....

List<IGH_GeometricGoo> geometry = new List<IGH_GeometricGoo>();

if ((!DA.GetDataList(0, geometry))) return;

any ideas?
