NHibernate - is property lazy loading possible?

I've got some binary data that I store and was going to separate this out into a separate table so it could be lazy loaded.

However, i then came across this post by Ayende (http://ayende.com/Blog/archive/2010/01/27/nhibernate-new-feature-lazy-properties.aspx) which suggests that property lazy loading is now possible.

I have added the lazy="true" attribute to my property mapping but the field is still loaded from the database (I am using a simple text field to test).

My query:

                return _session.CreateQuery("from Product")
                .SetMaxResults(1)
                .UniqueResult<Product>();

Mapping:

<property name="Description" type="string" column="FullDescription" lazy="true"/>

Has anyone been able to get this working? Personally I prefer this approach than having to add another table to my database.

As the article states: "This feature is now available on the NHibernate trunk". So either NH 3.0 or the latest trunk.

It will be possible on nhibernate 3.0, on the current version is not possible. You can download the trunk code or wait for the 3.0 version :-)
