This is how I did it mapping 2 entities to 1 table:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-
lazy="true" assembly="InExchange.Domain"
namespace="InExchange.Domain">
<class name="Invoice" table="ib_Invoice">
<id name="InvoiceId">
<generator class="native"></generator>
</id>
<!-- lazy load does not work with one-to-one relations -->
<many-to-one name="Data" column="InvoiceId" unique="true"
insert="false" update="false" cascade="save-update"></many-to-one>
</class>
</hibernate-mapping>
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-
lazy="true" assembly="InExchange.Domain"
namespace="InExchange.Domain">
<class name="InvoiceData" table="ib_Invoice">
<id name="InvoiceId">
<generator class="native"></generator>
</id>
<property name="BlobData"></property>
</class>
</hibernate-mapping>
Notice the insert="false" update="false" in the relation. I had to set
them to avoid multiple inserts and other strange behaviour. Also, on
insert, you must set the Data property to null before Save(), then
issue a Refresh() to let NH create a proxy object. Then you can access
InvoiceData.BlobField and then call Flush().
Maybe there is a better way though...

Johannes
