So here is the deal I have 2 tables that look like this...

User:
ID
Name

Address:
ID(User)
Type
Line1
Line2
....

Where the PK for Address is a combination of ID and Type.

Here is my mapping file...
Code:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
   auto-import="true">
  <class name="AutomatedGrantSuggestions.DataAccess.Organization, AutomatedGrantSuggestions.DataAccess" lazy="false" table="ct_org_master">
    <id name="CtId" column="ct_id">
      <generator class="native" />
    </id>
    <property name="Name" column="ct_org_name1"/>
    <property name="Name2" column="ct_org_name2"/>
    <many-to-one name="Address" class="AutomatedGrantSuggestions.DataAccess.Address, AutomatedGrantSuggestions.DataAccess"/>
  </class>
  <class name="AutomatedGrantSuggestions.DataAccess.Address, AutomatedGrantSuggestions.DataAccess" lazy="false" table="ct_org_address">
    <composite-id>
      <key-property name="CtId" column="ct_id" />
      <key-property name="Type" column="ct_org_addr_type"/>
    </composite-id>
    <property name="CtId" column="ct_id"/>
    <property name="Line1" column="ct_org_addr1"/>
    <property name="Line2" column="ct_org_addr2"/>
  </class>
</hibernate-mapping>


But when I run my tests I get the following error...
Quote:
Test 'AutomatedGrantSuggestions.DataAccess.Tests.OrganizationIntegrationTest.TestRetrieveHibernateFromIDWithAddress' failed:
Test method AutomatedGrantSuggestions.DataAccess.Tests.OrganizationIntegrationTest.TestRetrieveHibernateFromIDWithAddress threw exception: NHibernate.FKUnmatchingColumnsException: Foreign key (FK4961A1696CC0F1CB:ct_org_master [Address])) must have same number of columns as the referenced primary key (ct_org_address [ct_id, ct_org_addr_type]).

Any Ideas?

    <property name="Name" column="ct_org_name1"/>
    <property name="Name2" column="ct_org_name2"/>
    <bag name="AddressList" inverse="true" generic="true" lazy="true">
      <key>
        <column name="CtId" />
      </key>
      <one-to-many class="AutomatedGrantSuggestions.DataAccess.Address, AutomatedGrantSuggestions.DataAccess" not-found="ignore"/>
    </bag>
  </class>
  <class name="AutomatedGrantSuggestions.DataAccess.Address, AutomatedGrantSuggestions.DataAccess" lazy="false" table="ct_org_address">
    <composite-id>
      <key-property name="CtId" column="ct_id" />
      <key-property name="Type" column="ct_org_addr_type"/>
    </composite-id>
    <property name="Line1" column="ct_org_addr1"/>
    <property name="Line2" column="ct_org_addr2"/>
    <!--<many-to-one name="CtId" not-null="false"/>-->
  </class>
</hibernate-mapping>


This seems to work in case anyone else gets stuck...
