AutoMapper Exception - automapper

Question

This is a first time i have been bogged down like this by automapper. I am trying to map a result set returned by the stored procedure to my entity. L2S has the result set available, it is one row for my current test, can by multiple. Usually automaper exception is thrown when a return type is nullable if not properly handled. I have left it as is and also changed it to some value but in both cases i am still getting the exception. I am missing some thing very basic here but can't put my hands on it. Need second pair of eyes... Thanks.
Code Call
var annualReportOutreachEditionResult = ClientsContext.AnnualReportOutreachEditionInfoGet(fice, reportYear).ToList();
if (annualReportOutreachEditionResult != null)
{
annualReportOutreachEditionDetail = Mapper.Map<List<AnnualReportOutreachEditionInfoGetResult>, List<AnnualReportOutreachEditionDetail>>(annualReportOutreachEditionResult);
AnnualReportOutreachEditionDetail Entity
public class AnnualReportOutreachEditionDetail
{
public string Edition { get; set; }
public DateTime MailDate { get; set; }
public string CardId { get; set; }
}
AnnualReportOutreachEditionInfoGetResult L2S Entity
public partial class AnnualReportOutreachEditionInfoGetResult
{
private string _Edition;
private System.Nullable<System.DateTime> _MailDate;
private string _CardId;
public AnnualReportOutreachEditionInfoGetResult()
{
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_Edition", DbType="VarChar(50)")]
public string Edition
{
get
{
return this._Edition;
}
set
{
if ((this._Edition != value))
{
this._Edition = value;
}
}
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_MailDate", DbType="Date")]
public System.Nullable<System.DateTime> MailDate
{
get
{
return this._MailDate;
}
set
{
if ((this._MailDate != value))
{
this._MailDate = value;
}
}
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_CardId", DbType="Char(9)")]
public string CardId
{
get
{
return this._CardId;
}
set
{
if ((this._CardId != value))
{
this._CardId = value;
}
}
}
}
MApping
I have also checked/tested defaultvalue for date and my exception is still there. That is the only nullable type.
public static void MapAnnualReportOutreachEditionDetail()
{
Mapper.CreateMap<AnnualReportOutreachEditionInfoGetResult, AnnualReportOutreachEditionDetail>()
;
}

Answer 1

It was a problem at my end, I forgot to add the definition for my mapper method. Fixed.
