[MOXy] Mapping composite object into parent record

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>

                </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!

Hi Polly,

Nothing is jumping out at me, and yes, the self (".") mapping should work.  Can you please forward me your schema file?

Hi again Polly,

There is an issue with using self mappings ("." xpath) when a default namespace is set.  I've opened bug# 250952 to track this issue.
