WdCopyService Error: Node has no valid parent?

Question

I tried to do this:
WDCopyService.copyElements(wdContext.nodeResponse25(), wdContext.nodeHeader2());
However it gives the error:
"Node(DemoWSViewSearchOrder.Order.Header2): cannot bind or add elements because the node has no valid parent"
So I initiate the node with this:
     IPrivateDemoWSViewSearchOrder.IHeader2Element ele2 =
           wdContext.nodeHeader2().createHeader2Element();
     wdContext.nodeHeader2().addElement(ele2);
However it is still giving the error:
"Node(DemoWSViewSearchOrder.Order.Header2): cannot bind or add elements because the node has no valid parent"
Any idea why?

Hi
As you said :I initiate the node with this?
To get facility of WDCopyService no need to initiate any node belongs to model .Only care need to take is
Use this method after execution of the model  after executing and invalidating the response node of model,
updated data is there.  now u can either bind it to any table or copy it to another node using WDCopyService.
Regarding this error
Node(DemoWSViewSearchOrder.Order.Header2): cannot bind or add elements because the node has no valid parent
It need a identification of Source (which contain the updated data after executing the model), and target (where u want copy of this data)
read this carefully
@throws RuntimeException if target is a model node and
   *    source is not a model node holding the same class.
