In adapting the sample you have commented out the loading of the xml schema metadata. In so doing you have altered the dynamics of the sample to use SDOs generic XML behaviour. This means that as the SDO runtime reads your document it will build up the loosest form of metadata it can on the fly, in order that it does not preclude later content of document. It will therefore, when it first sees a shipTo element, model that as an isMany feature. I can't recall exactly how this goes now without digging back, it may also be that the document is modeled as an sdo Sequence (there are samples for Sequences if so). I suggest you either reintroduce the loading of the schema (if necessary, adapted to match your modified document), or take a look at the samples for generic XML and sequences. I hope this lets you advance, if not please post back.
