endDocument() called twice in DOM to SAX transform

           Summary: endDocument() called twice in DOM to SAX transform
           Product: XalanJ2
           Version: 2.4
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xalan.transformer
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


When transforming from a DOM node to SAX endDocument() in 
org.xml.sax.ContentHandler is wrongly called twice, as demonstrated by the 
program below.  It is first called from 
org.apache.xml.utils.TreeWalker.traverse and then from 
org.apache.xalan.transformer.TransformIdentityImpl.transform.


import javax.xml.parsers.*;
import javax.xml.transform.sax.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
import org.w3c.dom.*;

public class XalanTest2 {

  public static void main(String[] args) throws Exception {
    DocumentBuilderFactory builderFactory 
      = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = builderFactory.newDocumentBuilder();
    Document document = builder.newDocument();
    Element element = document.createElementNS(null, "test");

    TransformerFactory transformerFactory = TransformerFactory.newInstance();
      
    // Setup transformer to transform DOM to SAX
    Transformer transformer = transformerFactory.newTransformer();
    DOMSource source = new DOMSource(element);
    SAXResult result = new SAXResult(new TestHandler());
    
    transformer.transform(source, result);
  }

  private static class TestHandler extends DefaultHandler {
    public void endDocument() {
      System.out.println("endDocument() called");
    }
  }

}
