I´m trying to extends CharBooleanType to enable S/N chars as True/False but I get a compiler error:
The type 'NHibernate.Type.CharBooleanType' has no constructors defined

But my code is exactly the same as TruFalseType.cs and YesNoType.cs.
My NHibernate version is 1.0.2.0


using NHibernate.SqlTypes;

namespace NHibernate.Type
{
public class SNType : CharBooleanType
{
/// <summary></summary>
internal SNType()
: base(new AnsiStringFixedLengthSqlType(1))
{
}

/// <summary></summary>
protected override sealed string TrueString
{
get { return "S"; }
}

/// <summary></summary>
protected override sealed string FalseString
{
get { return "N"; }
}

/// <summary></summary>
public override string Name
{
get { return "SN"; }
}
}
}

Yes, its constructors are internal. Can you implement IUserType instead?

It´s Internal, I see now. :(

Any reason to do this?

Make it public would make our life easier and no BC.

Where can I suggest this to NHibernate team?

Yes I think we could make them public. JIRA (http://jira.nhibernate.org) is the place for such suggestions.
