validate() is called.

  selectionMgr = new SelectionMgr();
  
  public Document render(RequestContext context) throws Exception {
    Document document = XmlUtils.createDocument();
    selectionMgr.startRendering(context);
    for (int nodeIndex = 0; nodeIndex < nodeCount; nodeIndex++) {
      Object node = ...
      Element elem = renderElement(node);
      selectionMgr.renderButton(element, node);
    }
    selectionMgr.stopRendering();
    return document;
