Nhibernate back reference loads in one-to-one relation

Question

Hello. I Have one-to-one relation in my NHibernate mapping:

<many-to-one name="PersonProfile" not-null="true"
    class="PersonProfile" column="profile" cascade="all" lazy="proxy"/>
...
<one-to-one name="Owner" class="Person" property-ref="PersonProfile" 
    constrained="true" lazy="proxy"/>

PersonProfile class have batch-size attribute set. When user.PersonProfile property is hit batch load triggers. But then, when Owner property is loaded it loads from database. Why?

Answer 1

Because one-to-one relations can not be lazy loaded (in some circumstances).
