Orchard CMS module no values from Editor - orchardcms

Question

I've created my first simple module but for some reason my editor doesn't seem to be getting any values from the form.
The code is basically a slight modification on the Maps module example. (I've trimmed usings and whatnot for brevity.) The example is here: http://docs.orchardproject.net/Documentation/Writing-a-content-part
EDIT: I narrowed it down to my bool and DateTime properties. If I only use strings and ints my module works as expected. I have looked at other migrations in my modules directory and they use the generic Column method. I tried this, but still cannot get it to work.
Model:
namespace Maps.Models
{
public class MapRecord : ContentPartRecord
{
public virtual int SenderId { get; set; }
public virtual int RecipientId { get; set; }
public virtual string Subject { get; set; }
public virtual string Body { get; set; }
public virtual DateTime Timestamp { get; set; }
public virtual bool Read { get; set; }
public virtual int ReplyTo { get; set; }
}
public class MapPart : ContentPart<MapRecord>
{
[Required]
public int SenderId
{
get { return Record.SenderId; }
set { Record.SenderId = value; }
}
[Required]
public int RecipientId
{
get { return Record.RecipientId; }
set { Record.RecipientId = value; }
}
[Required]
public string Subject
{
get { return Record.Subject; }
set { Record.Subject = value; }
}
[Required]
public string Body
{
get { return Record.Body; }
set { Record.Body = value; }
}
[Required]
public DateTime Timestamp
{
get { return Record.Timestamp; }
set { Record.Timestamp = value; }
}
[Required]
public bool Read
{
get { return Record.Read; }
set { Record.Read = value; }
}
[Required]
public int ReplyTo
{
get { return Record.ReplyTo; }
set { Record.ReplyTo = value; }
}
}
}
Migrations.cs
public class Migrations : DataMigrationImpl {
public int Create() {
// Creating table MapRecord
SchemaBuilder.CreateTable("MapRecord", table => table
.ContentPartRecord()
.Column<int>("RecipientId")
.Column<int>("SenderId")
.Column<string>("Subject")
.Column<string>("Body")
.Column<DateTime>("Timestamp")
.Column<bool>("Read")
.Column<int>("ReplyTo")
);
ContentDefinitionManager.AlterPartDefinition(
typeof(MapPart).Name, cfg => cfg.Attachable());
return 1;
}
}

If this is similar to the example there could be two possible issues. 1) Maybe you haven't added the placement file. If the migration worked and there is no placement file then you won't see the data. 2) Another possible solution if the migration is failing would be that it doesn't have the correct DataTypes for bool and DateTime. Instead try DBType.Boolean and DBType.DateTime. Let me know if that works for you.
