HibernateAssembler problem loading object

Question

I'm using LCDS (LiveCycle Data Services) 2.5.1 and I am
trying to load a Java object using hibernate and have it given to
my flex client.
I followed this tutorial:
http://blog.comtaste.com/2007/07/livecycle_data_services_and_hi.html
Only issue is that when I attempt to use the DataService
object (in flex client) to do a "getItem" I get the following
error:
Missing identity properties: id
My "data-management-config.xml" has this:
<destination id="hibernatePerson">
<adapter ref="java-dao" />
<channels>
<channel ref="my-rtmp" />
</channels>
<properties>
<source>flex.data.assemblers.HibernateAssembler</source>
<scope>application</scope>
<metadata>
<identity property="id" />
</metadata>
<server>
<hibernate-entity>foo.bean.Person</hibernate-entity>
<update-conflict-mode>PROPERTY</update-conflict-mode>
<delete-conflict-mode>OBJECT</delete-conflict-mode>
<fill-configuration>
<use-query-cache>false</use-query-cache>
<allow-hql-queries>true</allow-hql-queries>
</fill-configuration>
</server>
</properties>
</destination>
Any ideas?

I got it. After reading some of the documentation on
DataService.getItem I learned that the "ItemReference" object that
is given back extends "AsyncToken". This means you should either
bind to the "result" property of the ItemReference or add a
responder to it (i.e. itemRef.addResponder).
Then once the data is retrieved your "result" or "fault"
methods (from the mx.rpc.IResponder interface) will be
invoked.
