--------------------------------------
The mapping you attached differs from what you describe. Also, please attach a simple failing test case.
> Incrementing a nullable <Version> field fails
> ---------------------------------------------
>
> Key: NH-788
> URL: http://jira.nhibernate.org/browse/NH-788
> Project: NHibernate
> Type: Bug
> Components: Core
> Versions: 1.2.0.Beta1
> Reporter: Jens Dein
> Priority: Minor
> Attachments: Serialno.hbm.xml
>
> I have defined my version tag like this :
> <version
> name="Hbversion"
> column="HBVersion"
> type="System.Int32"
> unsaved-value="null"
> />
> and in my class like this :
> private System.Int32? _hbversion;
> and when trying to persist the code I get an error in the following code :
> public class Int32Type : ValueTypeType, IDiscriminatorType, IVersionType
> public virtual object Next( object current )
> {
> return ( ( int )current ) + 1;
> }
> besause current is typecasted to int without checking for null. Code might be changed to the following :
> public virtual object Next( object current )
> {
> if (current == null)
> return Seed;
> else
> return ((int)current) + 1;
> }
> I hope I havent misunderstood totally how to use these nullables, but I believe I found advise on the net stating that it should be possible to do it this way in the 1.2 version.
> Using .NET 2.0 of course and SQL Server 2005.
