For some reason when I persist my instance the XML data is inverted. If anyone can tell me why this is happening and how to correct it I would greatly appreciate it.

The model looks like:

<xforms:model id=”rootModel”>

 <xforms:instance id=”my-instance”>

  <my-instance-main>

    <books>

     <book>

      <title/>

      <author/>

     </book>

    </books>

    <houses>

     <house>

      <address/>

      <sqfeet/>

     </house>

    </houses>

  </my-instance-main>

 </xforms:instance>

</xforms:model>

The data is persisted via:

<xforms:submission id="save-submission-xml" ref="xxforms:instance('my-instance')" resource="/exist/rest/db/orbeon/xforms-sr/addServers-instance.xml" method="put" replace="none">

</xforms:submission>

I don’t understand why the <houses> element is coming before the <books> element.

<my-instance-main>

<houses>

  <house>

   <address/>

   <sqfeet/>

  </house>

 </houses>

 <books>

  <book>

   <title/>

   <author/>

  </book>

 </books>

</my-instance-main>
