Default Error with Netscape and FireFox

Hi Everyone,

I'm hoping someone has faced this problem before and solved it... I've been pulling my hair out for a couple of days.

I have a webpage that has a number of divs on it... For each div I have set up an XmlHttpRequestObject that is called when the div is displayed, and retieves an XML stream from another page. It works fine in IE, but when I try this in FireFox, 1 of the tabs gives a wierd error, while the rest look fine.

The error is:

Error: [Exception... "Component returned failure code: 0x80040111
(NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]" nsresult: "0x80040111
(NS_ERROR_NOT_AVAILABLE)" location: "JS frame ::

I have checked the page which send the XML stream, and it seems to return a properly formatted XML doc. The error is occuring on the line where I check to ensure that the status of the request in 200.

Anyone have any ideas? I read something about using Plain Text for the response instead of XML, but am not sure if that will even work, or how I could implement it.

Any suggestions will be appreciated.

I finally got this figured out last night... It was a combination of my own stupidity and what I understand is a feature in firebug.

In case anyone else ever runs into something like this, here is what I did that broke it.

I changed ideas part way through coding this page, and ended up with a duplicated call to a specific function, which was the one that originally made the call to the page with the XML feed. While IE seems to handle this kind of thing well, it appears that FireFox somehow got confused between the duplicated call, and returned 0 as the status on the XMLHttpRequest object.

This then combined with something in Firebug to give an error that had something to do with an object not being initialized and loaded. I ended up working back from the last problem to the first, which would seem contrary to my usual methodology, but worked out in this case.

Hopefully that will help anyone who might face similar problem.
