JSF AJAX post-back

Question

I have a javascript function for a POST request from XMLHttprequest object.The post-back is handled within the decode function of the component which generates the AJAX request. The javascript request looks as follows:
function lookup(field) { .... if (window.XMLHttpRequest) { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); } var formdata = "ajaxreq=true"; " var formAction = window.document.forms[0].action;\n" + "req.open(\"POST\",formAction,true);\n" + "req.setRequestHeader(\"Content-Type\",\"application/x-www-form-urlencoded\");\n" + req.onreadystatechange = processXMLResponse; req.send(formdata); } This request is generated from within the directoryBrowser.jsp itself. This request is not being recognized as a post-back by the JSF framework ,successful as it is not causing the decode method of the component to be executed. What is wrong? When i print out the responseText of the request object from the callback function, i get teh html of the page printed out.The responsexml is null.

Maybe, you've already solved the problem.
Anyway, I faced with a similar problem and (after days of debugging and googling) I solved it making the request object local rather than globa (and changing the request callback accordingly)l.
function sendRequest()
  var req = createRequestObject(); // e.g. new XMLHttpRequest();
  req.open('GET', url, true);
  req.onreadystatechange = function{ handleRequest(req); };
  req.send(null);
function handleRequest(req)
  if (req.readyState == 4)
    if (req.status == 200)
      // request done
}Hope this help!!
