Problem with Base Class Generics

Hibernate version: 1.2.0.2001

Hi,
I have a problem ...
I have one base class and 2 classes who inherit from this class.
Now this base class is this:

Code:

public class Category<ParentType>
        where ParentType : Category<ParentType>
        
    {
        private Guid m_id;
        private ParentType m_parentCategory;
        private string m_name;
        private string m_description;

        #region Category Properties
        #region Category Constructors
    }
}

My other 2 classes:
public class UnitCategory : Category<UnitCategory>
public class StockItemCategory : Category<StockItemCategory>

As you can see there is a generic type that has to be given when creating it.
Now there is a problem when mapping this file..
Now I have this:
<class name="Category'1[???]" table="Categories">

What do I have to insert in place of the question marks?? Otherwise it can not map the file, which is logic.
Can anyone help me??
Thanks in advance...

I don't believe you need to specify the bracketed part '[???]'. I don't usually this but try this and see how it works for you

Code:

Hope this helps

it seems that hibernate doesn't support yet generics in the way i used them.
my solution was that i didnt map the base class, but only the subclasses.
with a small change in de database and putting virtual before every properitie and method, everything worked perfect.

Ah...sounds like you are dealing with limitations of the version of Dynamic Proxy that NHibernate uses in regard to generics.
