Business Object sublist properties are not visible

Vasily Himchenko

I create the report via code and register Business Object as datasource. Business object contains sub-list (subreport source):

public class SubData
{
    ....
}

public class Data
{
    public Int32 Id{get;set;}
    public String Name{get;set;}
    public List<SubData> List{get;set;}
}

In the code

Data data = new Data();
data.List = new List<SubData>();

List<Data> reportData = new List<Data>();
reportData.Add(data);
....

using (FastReport.Report report = new FastReport.Report())
{
      report.RegisterData(reportData, "Data", 5);
      report.GetDataSource("Data").Enabled = true;
      report.Design(true);
}

As result I see in the Data Sources: "Data" and DataFields "Id" and "Name", but the "List" absent.

In the main menu (Data->Choose Report Data...) I could find and select the List data to show, but how to do this via C# code?
