[jibx-users] problem with collection in abstract mapping

[Joerg Buchberger]

Hi all.
One of my mappings is abstract and contains one collection.
Some sub mappings extend that abstract mapping.
The purpose behind is to resemble a tree-like structure.
The binding is used for a jibxsoap-based webservice.
The java objects are setup correctly, with dozens of children nodes 
upto a depth of 5. But, when being marshalled, I got only the top two 
hierarchy levels, which looked like so, unfortunately:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/";>
<SOAP:Body>
  <site>
    <base id="1" name="London-II">
      <comment>Turbine-Gen</comment>
      <child>
        <site>
          <base id="2" name="PLANT pumps">
            <comment></comment>
          </base>
        </site>
        <site>
          <base id="554" name="PLANT fans">
            <comment></comment>
          </base>
        </site>
      </child>
    </omt>
  </site>
</SOAP:Body>
</SOAP:Envelope>
When I really would have expected something like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/";>
<SOAP:Body>
  <site>
    <base id="1" name="London-II">
      <comment>Turbine-Gen</comment>
      <child>
        <site>
          <base id="2" name="PLANT pumps">
            <comment></comment>
          <child>
            <machine>
              <base id="6" name="pump a">
                <comment></comment>
              </base>
              <power>110.0</power>
              <speed>358.0</speed>
            </machine>
            <machine>
              <base id="9" name="pump b">
                <comment></comment>
              </base>
              <power>114.0</power>
              <speed>351.0</speed>
            </machine>
            <machine>
              <base id="17" name="pump c">
                <comment></comment>
              </base>
            </machine>
              <power>104.0</power>
              <speed>381.0</speed>
          </child>
          </base>
        </site>
        <site>
          <base id="554" name="PLANT fans">
            <comment></comment>
          </base>
        </site>
      </child>
    </base>
  </site>
</SOAP:Body>
</SOAP:Envelope>
This is my simplified mapping:
<?xml version="1.0" encoding="UTF-8"?>
<binding>
  <mapping name="omt" class="nik.data.tree.Node" abstract="true">
    <value style="attribute" name="id" field="nodeId" />
    <value style="attribute" name="name" field="nodeName" />
    <value name="comment" field="treeComment" />
    <collection name="child" field="Children" usage="optional" />
  </mapping>
  <mapping name="site" class="nik.data.tree.LocationNode" 
extends="nik.data.tree.Node" >
    <structure map-as="nik.data.tree.Node" />
  </mapping>
  <mapping name="machine" class="nik.data.tree.MachineNode" 
extends="nik.data.tree.Node">
    <structure map-as="nik.data.tree.Node" />
    <value name="power" field="power" />
    <value name="speed" field="speed" />
  </mapping>
</binding>

Thanks for any help.

Joerg
