Hi,

I have a issue which is kinda interesting. i am using NH 1.2.1 with .NET 2.0

I have a C# class with a virtual property that returns a nullable type .

Class A
{
private byte? _byte;
Public virtual byte? prop1
{
get {return _byte;}
set {_byte=value;}
}
}

The HBM mapping file for this class has the the PROPERTY data type as byte( a normal C# byte).
The DB table for this class accepts null values for the field.

But when i try to insert NULL values , the system does not give me an error, because the mapping file does not have a nullable data type.
Why is this so?
Please explain. I tried this with all primitive types.

Remove the type from the mapping. NHibernate should be able to infer the type from the class property the mapping refers to.

See if that works.

Cheers,

Symon.
