Problem setting nullable in IPropertyConvention

Hi,

I've come upon a strange issue when trying to create a convention to map Non Null columns. I've tested this on build 689 and get the same problem. The code is as follows

Public Class RequiredConvention
    Implements IPropertyConvention
    Implements IPropertyConventionAcceptance

    Public Sub Accept(ByVal criteria As FluentNHibernate.Conventions.AcceptanceCriteria.IAcceptanceCriteria(Of FluentNHibernate.Conventions.Inspections.IPropertyInspector)) Implements FluentNHibernate.Conventions.IConventionAcceptance(Of FluentNHibernate.Conventions.Inspections.IPropertyInspector).Accept
        criteria.Expect(Function(x) x.Property.MemberInfo.IsDefined(GetType(RequiredAttribute), False))
    End Sub

    Public Sub Apply(ByVal instance As IPropertyInstance) Implements IConvention(Of FluentNHibernate.Conventions.Inspections.IPropertyInspector, FluentNHibernate.Conventions.Instances.IPropertyInstance).Apply

        instance.Not.Nullable()

    End Sub

End Class

The error I receive is

Error 2 'Nullable' is ambiguous across the inherited interfaces 'FluentNHibernate.Conventions.Inspections.IPropertyInspector' and 'FluentNHibernate.Conventions.Instances.INullableInstance'. E:\Data\Dev\TS\EDC\Trunk\Repository\Mappings\SM\Conventions\RequiredConvention.vb

Any ideas what I'm doing wrong?

Thanks

James

    Using VB, I'm afraid.

    Try explicitly casting instance to INullableInstance.
