I have do in ajax a script that call a file xml.
But in firebug i receive this error:
uncaught exception: [Exception... "Component returned failure code: 0xc1f30001 (NS_ERROR_NOT_INITIALIZED) [nsIXMLHttpRequest.send]" nsresult: "0xc1f30001 (NS_ERROR_NOT_INITIALIZED)" location: "JS frame :: javascript: eval(__firebugTemp__); :: anonymous :: line 1" data: no]

And this:

[Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: http://nerto.it/ajax.js :: anonymous :: line 69" data: no]


At line 69 of my file there is:
Code:
	receiveReq.onreadystatechange = function(){
line69:				if (receiveReq.readyState == 4&&receiveReq.status == 200) {
					xmldoc = receiveReq.responseXML;
					if(serviceChat)chatReceive();
					if(serviceTop)topReceive();
					if(serviceLast)lastReceive();
					if(serviceCosasifa)cosasifaReceive();
					if(serviceLocalita)localitaReceive();
					if(serviceControlloEsistenza)esistenzaReceive();
					return false;
				}
				
			}
			receiveReq.send(null);
Where is the problem?
Thanks
