Dear All,

unfortunately I cannot serialize items using DOM/LS.
I get an NullPointerException because Node.getParentNode() returns null.

Here's the use-case:



public class Test
{
        public static void main(String[] args) throws Exception
        {
                System.setProperty("org.basex.path", "D:\\ODX-Development-Neu\\odx-workspace\\.database");
                Context context = new Context();

                try
                {
                        //
                        // open DB and query an item
                        //
                        new Open("vag").execute(context);
                        QueryProcessor queryProcessor = new QueryProcessor("//BASE-VARIANT[SHORT-NAME='BV_EnginContrModul1UDS']", context);
                        Item item = queryProcessor.iter().next();

                        //
                        // serialize item, proofs that result is here
                        //
                        Serializer serializer = queryProcessor.getSerializer(System.out);

                        // can the queryProcessor be closed here?
                        queryProcessor.close();

                        serializer.serialize(item);
                        serializer.close();

                        //
                        // write with DOM fails!!!
                        //
                        org.w3c.dom.Node node = (org.w3c.dom.Node)item.toJava();

                        DOMImplementationLS domImplementationLS = (DOMImplementationLS)DOMImplementationRegistry.newInstance().getDOMImplementation("LS");
                        LSOutput lsOutput = domImplementationLS.createLSOutput();
                        lsOutput.setByteStream(System.out);
                        LSSerializer lsSerializer = domImplementationLS.createLSSerializer();
                        lsSerializer.getDomConfig().setParameter("format-pretty-print", Boolean.TRUE);
                        lsSerializer.write(node, lsOutput);

                }
                finally
                {
                        context.close();
                }
        }
}


And the exception:

Caused by: java.lang.NullPointerException
        at com.sun.org.apache.xml.internal.serialize.DOMSerializerImpl.prepareForSerialization(DOMSerializerImpl.java:1064)
        at com.sun.org.apache.xml.internal.serialize.DOMSerializerImpl.write(DOMSerializerImpl.java:747)
        ... 1 more


I am using the latest snapshot: BaseX76-20130131.202759


Can you help me?
