Nullable types in Crystal report

I am using asp.net mvc and crystal reports v.13.

i have two class which contains nullable variables.

public class CustomerList
{
    public List<customerinfo> custInfo{ get; set; }
}
public class customerinfo
{
    public string name{ get; set; }
    public Nullable<int> id { get; set; }
    public Nullable<int> age{ get; set; }
}

A list of objects of above class (CustomerList) is set in data source of crystal report.

rd.SetDataSource(rptSource);

In crystal reports i am selecting the same class from database expert using .net Objects.

Since i am using nullable variable i am getting the following error:

"DataSet does not support System.Nullable<>."
