I used this How do you map an enum as an int value with fluent NHibernate? to map in the past but I've recently upgraded to NHibernate 3 and this doesn't seem to work anymore. I've put breakpoints in my EnumConvention class and they're not being hit. The query that is hitting the database has the enum as a string which is the default configuration.
How does this work with NHibernate 3?
Update
Here is part of the mapping file that is generated:
<property name="ComponentType" type="FluentNHibernate.Mapping.GenericEnumMapper`1[[...ComponentType, ..., Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], FluentNHibernate, Version=1.1.0.0, Culture=neutral, PublicKeyToken=8aa435e3cb308880">
<column name="ComponentTypeId" />
</property>
It doesn't seem right that it would be using a GenericEnumMapper
when an IUserTypeConvention
is specified for enums.
Here is my convention:
public class EnumConvention : IUserTypeConvention
{
public void Accept( IAcceptanceCriteria<IPropertyInspector> criteria )
{
criteria.Expect( e => e.Property.PropertyType.IsEnum );
}
public void Apply( IPropertyInstance instance )
{
instance.CustomType( instance.Property.PropertyType );
}
}

Simply doing
Map( m => m.MyEnum ).CustomType<MyEnum>()
seems to work just fine now.If anyone knows why
IUserTypeConvention
doesn't work with Fluent NHibernate in NHibernate 3, I'd still like to know why. Maybe it's because mapping the custom type to the enum works now, but why wasn't it removed from the lib then?
