Transferring a Node with multiple elements

Question

Hi there, Just want to ask the experts out there am I doing the right coding to transfer all elements of a node to another node? Thanks for your guidance!
     for (int n =0; n < wdContext.nodeItem().size();n++) {
          IPublicDemoWSController.ISa_Item3Element ele = wdContext.nodeSa_Item3().currentSa_Item3Element();
          ele.setEMESS(wdContext.nodeItem().getElementAt(n).getAttributeValue("EMESS").toString());
          wdContext.currentSa_Item3Element().setITM_NUMBER(wdContext.nodeItem().getElementAt(n).getAttributeValue("ITM_NUMBER").toString());
          wdContext.currentSa_Item3Element().setKUNAG(wdContext.nodeItem().getElementAt(n).getAttributeValue("KUNAG").toString());
          wdContext.currentSa_Item3Element().setKUNRE(wdContext.nodeItem().getElementAt(n).getAttributeValue("KUNRE").toString());
          wdContext.currentSa_Item3Element().setKUNRG(wdContext.nodeItem().getElementAt(n).getAttributeValue("KUNRG").toString());
          wdContext.currentSa_Item3Element().setKUNVE(wdContext.nodeItem().getElementAt(n).getAttributeValue("KUNVE").toString());
          wdContext.currentSa_Item3Element().setKUNWE(wdContext.nodeItem().getElementAt(n).getAttributeValue("KUNWE").toString());
          wdContext.currentSa_Item3Element().setMATERIAL(wdContext.nodeItem().getElementAt(n).getAttributeValue("MATERIAL").toString());
          wdContext.currentSa_Item3Element().setPLANT(wdContext.nodeItem().getElementAt(n).getAttributeValue("PLANT").toString());
          wdContext.currentSa_Item3Element().setREF_1(wdContext.nodeItem().getElementAt(n).getAttributeValue("REF_1").toString());
          wdContext.currentSa_Item3Element().setSALES_UNIT(wdContext.nodeItem().getElementAt(n).getAttributeValue("SALES_UNIT").toString());
          wdContext.currentSa_Item3Element().setSHORT_TEXT(wdContext.nodeItem().getElementAt(n).getAttributeValue("SHORT_TEXT").toString());
          wdContext.currentSa_Item3Element().setSTORE_LOC(wdContext.nodeItem().getElementAt(n).getAttributeValue("STORE_LOC").toString());
          wdContext.currentSa_Item3Element().setTARGET_QTY(wdContext.nodeItem().getElementAt(n).getAttributeValue("TARGET_QTY").toString());
          wdContext.currentSa_Item3Element().setTARGET_QU(wdContext.nodeItem().getElementAt(n).getAttributeValue("TARGET_QU").toString());
          wdContext.nodeSa_Item3().addElement(wdContext.currentSa_Item3Element());

Hey guys this is the summary of what I am doing so far:
Hi, I am hoping to get some help on this. I am trying to transfer element values from one model Node to another model Node. It sounds simple but maybe I am not really sure of the working of nodes and elements and it is giving me some trouble.
I have bind the model to the context:
          Request_Sa_Change request15 = new Request_Sa_Change(model4);
          Sa_Change sachange = new Sa_Change(model4);
          Sa_Header saheader2 = new Sa_Header(model4);
          Sa_Item saitem2 = new Sa_Item(model4);
          ArrayOfSa_Item arrayItem = new ArrayOfSa_Item(model4);
          arrayItem.addSa_Item(saitem2);
          sachange.setHeader(saheader2);
          sachange.setItem(arrayItem);
          request15.setSa_Change(sachange);
          wdContext.nodeRequest_Sa_Change().bind(request15);
Therefore there is already an element being initiated, so I have to set values into this created element before I can create a new one for the next element of values.
From my experiment with the codes below, I find that EVEN after I create and added a new Element into the node, the CurrentNode is still holding the same value of the previous element I create.
This lead me to believe that this is the reason after I execute the model, I got the error "ItemNum is Missing".          
     for (int n = 0; n < wdContext.nodeSa_Item().size(); n++) {
                    DemoWSOrder model = new DemoWSOrder();
                    Sa_Item item = new Sa_Item(model);
                    IPublicDemoWSController.ISa_Item3Element ele =
                         (IPublicDemoWSController.ISa_Item3Element) wdContext.nodeSa_Item3().currentSa_Item3Element();
                    wdComponentAPI.getMessageManager().reportException("" + wdContext.nodeSa_Item3().currentSa_Item3Element().getITM_NUMBER(), true);
                    ele.setEMESS(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getEMESS());
                    ele.setITM_NUMBER(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getITM_NUMBER());
                    ele.setKUNAG(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getKUNAG());
                    ele.setKUNRE(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getKUNRE());
                    ele.setKUNRG(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getKUNRG());
                    ele.setKUNVE(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getKUNVE());
                    ele.setKUNWE(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getKUNWE());
                    ele.setMATERIAL(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getMATERIAL());

                    ele.setSTORE_LOC(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getSTORE_LOC());
                    ele.setTARGET_QTY(wdContext.nodeSa_Item().getSa_ItemElementAt(n).getTARGET_QTY());
