Hello everyone,

I just finish creating a Ajax grid and for some reason I get an internal server error and was wondering what it really meant!!!

I’ll post you the code were the error occurs


function handleGridPageLoad()
{
  // when readyState is 4, we read the server response
  if (xmlHttp.readyState == 4)
  {
    // continue only if HTTP status is "OK"
    if (xmlHttp.status == 200)
    {    
      // read the response
      response = xmlHttp.responseText;
      // server error?
      if (response.indexOf("ERRNO") >= 0 
          || response.indexOf("error") >= 0
          || response.length == 0)
      {
        // display error message
        alert(response.length == 0 ? "Server serror." : response);
        // exit function
        return;
      }
      // the server response in XML format
      xmlResponse = xmlHttp.responseXML;        
      // browser with native functionality?    
      if (window.XMLHttpRequest && window.XSLTProcessor && 
          window.DOMParser)
      {      
        // load the XSLT document
        var xsltProcessor = new XSLTProcessor();
        xsltProcessor.importStylesheet(stylesheetDoc);
        // generate the HTML code for the new page of products
        page = xsltProcessor.transformToFragment(xmlResponse, document);
        // display the page of products
        var gridDiv = document.getElementById(gridDivId);
        gridDiv.innerHTML = "";
        gridDiv.appendChild(page);
      } 
      // Internet Explorer code
      else if (window.ActiveXObject) 
      {
        // load the XSLT document
        var theDocument = createMsxml2DOMDocumentObject();
        theDocument.async = false;
        theDocument.load(xmlResponse);
        // display the page of products
        var gridDiv = document.getElementById(gridDivId);
        gridDiv.innerHTML = theDocument.transformNode(stylesheetDoc);
      }
    } 
    else 
    {          
      alert("Error reading server response");
    }
  } 
}

Thank you for your help!
