Call to XercesDocumentWrapper method mapNode results in a pure virtual method called error

[T A <te...@yahoo.com>]

Hi, 
 
I am trying to use the XercesDocumentWrapper method mapNode to convert a Xalan Node to a Xerces Node. The Xalan node is obtained from a NodeRefList object via the item method.
 
The code is aborting at the call to map node and I see an error message "pure virtual method called"
 
Below is a code fragment. I would appreciate any help. Am I missing some kind of macro declaration or object?
 
 
        XALAN_CPP_NAMESPACE_USE
        XALAN_USING_XERCES(XMLException)
        XercesDOMSupport theDOMSupport;
        try
        {
                if (nodeList)
                {
                        DOMDocument* xercesDocument = sourceDocument->getDocument();
                        DOMNode* indexedNode;
                        XercesDocumentWrapper xalanDocument(xercesDocument);
                        
                        const NodeRefList::size_type nodeListLength = nodeList->getLength();
                        ctrace << "Node List Length is" << nodeListLength << endl;
                         XalanNode* the_node = nodeList->item(index);
 
                        if(the_node)
                             indexedNode = (DOMNode*)(xalanDocument.mapNode(the_node)); 
 
 
Thanks,
Ted

Well, what I am trying to do seems like it is a rather common operation from looking thru the archives, and following those examples I get this error. 
 
Perhaps someone has some example of this kind of operation and can share it? It seems like a bit of overkill to have to go and file a bug report when I believe that is might just be an error in the way I am using the API, and not some kind of systemic problem
 
In fact here is the thread that I followed and it seems that it worked for that person

A fragment can't help us figure out what's wrong. The best thing is to 
create a small, standalone program that can reproduce the problem, open a 
Jira bug report, and attach your sample program along with any data 
necessary to run it.
