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.
