[eclipselink-users] [MOXy] Mapping composite object into parent record

[amphoras <polly.c.chang@xxxxxxxxx>]

Hi,

Argh!  I am trying to map a composite object into the parent record like
documented here:
http://wiki.eclipse.org/Introduction_to_XML_Mappings_(ELUG)#XML_Composite_Object_Mapping

I have an Address element, and I'm trying to map the "Line" elements inside
it to another object called "AddressLine".  This is not working.  The object
"addressLine" is always null.

My XML looks like:
<Address ...>
  <AttentionOfName>Jane Doe</AttentionOfName>
  <CareOfName></CareOfName>
  <LineOne>101 Main Street</LineOne>
  <LineTwo>Apt 514</LineTwo>
  <LineThree>P.O. Box 123123</LineThree>
  <LineFour>Suite 1234</LineFour>
  <CityName>Malibu</CityName>
  <StateCode>CA</StateCode>
  <CountryCode>USA</CountryCode>
  <PostalCode>90914-2938</PostalCode>
</Address>

My project.xml file looks like:
		<class-mapping-descriptor xsi:type="xml-class-mapping-descriptor">
			<class>com.infor.common.model.fields.AddressLines</class>
			<alias>AddressLines</alias>
			<events xsi:type="event-policy"/>
			<querying xsi:type="query-policy"/>
			<attribute-mappings>

<default-namespace-uri>http://www.foo.com/bar/baz</default-namespace-uri>
			</namespace-resolver>
			<schema xsi:type="schema-file-reference">
				<schema-context>/Address</schema-context>
				<node-type>complex-type</node-type>
			</schema>
		</class-mapping-descriptor>

This mapping looks to me to be the XML equivalent of the examples that I saw
in code.  So why doesn't this work?  I saw the one note in the documentation
that said "The nodes mapped to by the composite object must be sequential. " 
I am not 100% sure what this means, but I did make sure that all the nodes
in Address and AddressLine are in the right order.  In addition, I debugged
into this but can't figure out why the "." mapping to AddressLine is never
used.  The eclipselink.moxy.test project uses this, so it looks like this is
definitely supposed to be supported.  But I want to do this with XML, not
with code.  

Can someone tell me what is wrong with this mapping?

Thanks!
