Weird results when adding or validating nt:file-Node

Question

Hello,
I'm trying to add the absolute path: /content/2012/201212/20121219_lh_lu_1442.pdf/jcr.content/renditions/original/jcr.content by this code:
Node parentNode = session.getNode("/content");
              Verbose.message(3,"Add node " + folders[folders.length-1]);
        if (session.nodeExists(parentNode.getPath()+"/"+"2012"))  {
            parentNode = session.getNode(parentNode.getPath()+"/"+"2012");
            Verbose.message(3,parentNode.getPath() + " already there");
        else  {
            parentNode = parentNode.addNode("2012", "sling:OrderedFolder");
           Verbose.message(3,parentNode.getPath() + " created");
        if (session.nodeExists(parentNode.getPath()+"/"+"201212"))  {
            parentNode = session.getNode(parentNode.getPath()+"/"+"201212");
            Verbose.message(3,parentNode.getPath() + " already there");
        else  {
            parentNode = parentNode.addNode("201212", "sling:OrderedFolder");
           Verbose.message(3,parentNode.getPath() + " created");
        // dam:Asset-Node named with the PDF-Name
        Verbose.message(3,"Add node 20121219_lh_lu_1442.pdf ");
        if (session.nodeExists(parentNode.getPath()+"/"+"20121219_lh_lu_1442.pdf")  {
            parentNode = session.getNode(parentNode.getPath()+"/"+"20121219_lh_lu_1442.pdf");
            Verbose.message(3,parentNode.getPath() + " already there");
        else  {
            parentNode = parentNode.addNode("20121219_lh_lu_1442.pdf", "dam:Asset");
            Verbose.message(3,parentNode.getPath() + " created");
        // jcr:content
        if (session.nodeExists(parentNode.getPath()+"/"+"jcr.content"))  {
            parentNode = session.getNode(parentNode.getPath()+"/"+"jcr.content");
            Verbose.message(3,parentNode.getPath() + " already there");
        else  {
            parentNode = parentNode.addNode("jcr.content", "dam:AssetContent");
            session.save();
            Verbose.message(3,parentNode.getPath() + " created");
        // metadata
        Node metadata=null;       
        if (session.nodeExists(parentNode.getPath()+"/"+"metadata"))  {
            metadata = session.getNode(parentNode.getPath()+"/"+"metadata");
            Verbose.message(3,metadata.getPath() + " already there");
        else  {
            metadata=parentNode.addNode("metadata", "nt:unstructured");
            session.save();
            Verbose.message(3,metadata.getPath() + " created");
        // renditions
        if (session.nodeExists(parentNode.getPath()+"/"+"renditions"))  {
            parentNode = session.getNode(parentNode.getPath()+"/"+"renditions");
            Verbose.message(3,parentNode.getPath() + " already there");
        else  {
            parentNode = parentNode.addNode("renditions", "nt:folder");
            Verbose.message(3,parentNode.getPath() + " created");
        listChildren("--->", parentNode );
        // orignal
        Verbose.message(3,"Create node " + parentNode.getPath()+"/"+"orignal - Exists=" + session.itemExists(parentNode.getPath()+"/"+"orignal"));
        if (session.nodeExists(parentNode.getPath()+"/"+"orignal"))  {
            parentNode = session.getNode(parentNode.getPath()+"/"+"orignal");
            Verbose.message(3,parentNode.getPath() + " already there");
        else  {
            parentNode = parentNode.addNode("orignal", "nt:file");
            parentNode.addNode("orignal", "nt:file");
            Verbose.message(3,parentNode.getPath() + " created");
        // jcr:content
        Verbose.message(3,"Add node 'jcr.content' to " + parentNode.getPath());
        if (session.nodeExists(parentNode.getPath()+"/"+"jcr.content"))  {
            parentNode = session.getNode(parentNode.getPath()+"/"+"jcr.content");
            Verbose.message(3,parentNode.getPath() + " already there");
        else  {
            parentNode = parentNode.addNode("jcr.content", "nt:resource");           
//            session.save();
            Verbose.message(3,parentNode.getPath() + " created");
        session.save();
        return parentNode.getPath();
    private static void listChildren(String indent, Node node ) throws RepositoryException {
        System.out.println("-->" + indent + node.getName()+ " Exists=" + session.nodeExists(node.getPath()));
        NodeIterator ni = node.getNodes();
        while(ni.hasNext()) {
            Node nextNode=ni.nextNode();
            listChildren(indent+"  ", nextNode);
            String NAME = nextNode.getName();
(Just to avoid irritations; the Verbose class does the logging.)
My program fails in the line "parentNode = parentNode.addNode("orignal", "nt:file");" with the messages:

I've no idea, why this program fails. The node ../original is already there; have added it with CRXDE Explorer. Saving there didn't work before adding jcr.content with the property "jcr:data". But now you can see that there is a difference in the validating the existence of the relative path "original" in the ongoing routine (results in "Exists=false") and in the "listChildren-method" called immediately after validating the "renditions". This routines results in "Exists=true" for the node "original".
So I've got two questions left: What do I need to do to add the node with the WebDAV-Connected program and how can I make sure it recognizes correctly the existence of a node
best regards,

I am not sure why you have used addNode method on same parentNode two times (line by line) because you already have added node in first line and now you have to save it. May be this is causing issue.
parentNode = parentNode.addNode("orignal", "nt:file"); 
parentNode.addNode("orignal", "nt:file");
let me know if it does not help you.
