Buggy source:
public void processOverlay(String overlaySrc,org.pentaho.ui.xul.dom.Document targetDocument,XulDomContainer container) throws XulException {
  final Document doc=getDocFromClasspath(overlaySrc);
  Element overlayRoot=doc.getRootElement();
  for (  Object child : overlayRoot.elements()) {
    Element overlay=(Element)child;
    String overlayId=overlay.attributeValue("String_Node_Str");
    org.pentaho.ui.xul.dom.Element sourceElement=targetDocument.getElementById(overlayId);
    if (sourceElement == null) {
      logger.warn("String_Node_Str" + overlayId + "String_Node_Str");
      continue;
    }
    for (    Object childToParse : overlay.elements()) {
      logger.info("String_Node_Str" + overlayId);
      parser.reset();
      parser.setContainer(container);
      XulComponent c=parser.parse((Element)childToParse,(XulContainer)sourceElement);
      sourceElement.addChild(c);
      ((XulContainer)sourceElement).addComponent(c);
      ((XulContainer)sourceElement).addChild(c);
      logger.info("String_Node_Str" + c);
    }
  }
}
