[Compass-developer] mapping problem

[matthew b. <bil...@ho...>]

Hi!
I am having problems with a parent-child mapping that should be  
simple but for the life of me I just cannot figure out what I am  
doing wrong!

The mapping below works fine. I can query 'male' and all male people  
and staff are returned - fantastic!

<compass-core-mapping>
     <class name="a.b.x.Person" alias="person">
         <id name="id"/>
         <property name="gender">
             <meta-data>gender</meta-data>
         </property>
     </class>
     <class name="a.b.x.Staff" alias="staff">
         <id name="id"/>
         <property name="number">
             <meta-data>number</meta-data>
         </property>
         <component name="identity" ref-alias="person"/>
     </class>
</compass-core-mapping>

When I advance a little using the mapping below I get stuck! I now  
query 'male' and get no hits returned. A query using initials that  
definitely exist in my database also returns no hits (I was hoping to  
get some people and staff returned).

<compass-core-mapping>
     <class name="a.b.x.Person" alias="person">
         <id name="id"/>
         <property name="gender">
             <meta-data>gender</meta-data>
         </property>
         <component name="names" ref-alias="personName"/>
     </class>
     <class name="a.b.y.PersonName" alias="personName" root="false">
         <property name="initials">
             <meta-data>initials</meta-data>
         </property>
     </class>
     <class name="a.b.x.Staff" alias="staff">
         <id name="id"/>
         <property name="number">
             <meta-data>number</meta-data>
         </property>
         <component name="identity" ref-alias="person"/>
     </class>
</compass-core-mapping>

I have probably made a mistake somewhere (or missed the point). Any  
help or advice would be appreciated.

Thanks - Matt
