Why Onreadystatechange method is not called on IE7 ?
I am filling a list dynamically from server with Ajax. I am having the following problem. Method onreadystatechage on server request is not called in IE7 (Internet explorer 7) the second time I invoke the method.
The code works in IE6, FFox, Opera, Safari.
..........
if(request && request.readyState < 4)
request.abort();
if(!window.XMLHttpRequest)
request = new ActiveXObject("Microsoft.XMLHTTP");
preFunc();
request.onreadystatechange = processRequestChange;
request.open("POST", uriFunc(), true);
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
request.setRequestHeader("Accept-Charset", "utf-8");
request.send(constructPostParamsFunc());

//THIS IS NOT INVOKED!!!!!!
request.onreadystatechange = processRequestChange;
request.open("POST", uriFunc(), true);
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
request.setRequestHeader("Accept-Charset", "utf-8");
request.send(constructPostParamsFunc());

Open method resets all properties of Request object on IE7.
Calling the open method initializes the request object. If you have set properties (such as onreadystatechange) it is reset to initial default values (NULL). So, do all your initialization between OPEN and the final call to SEND.
