Barracuda: NullPointerException when importing a node

Hi all,

I am getting the following stack trace while trying to import a node that I have dynamically extracted from an html page using JTidy.

This is the bit of code which is in a model:

      Node node = item.getNode();
      Document doc = getViewContext().getElementFactory().getDocument();
      node = doc.importNode( node, true );
      Element td = doc.getElementById("webhook");
      if ( td != null )
      {
        td.removeAttribute("id");
        td.appendChild( node );
        return new BComponent();
      }

The NullPointerException originates from the importNode call. 

Any ideas? Can I import a node that I have extracted using JTiday into a document that was compiled with XMLC and is using the lazy dom?

Cheers,

Adam.
