Hi Michael,

the problem should be fixed with the latest snapshot.

Dear Michael,

could you provide us with a small, self-contained example that allows us to reproduce the bug?

Thanks; greetings to my home town, Christian ___________________________

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?
