Components is not defined

[Saphod]

Hi,

I am using WordPress, and I always get a "Components is not defined"
error whenever the SACK functionality (AJAX) seems to be used.

As I have posted this issue on my website and got some additional
comments, I would like you to visit my post under

http://www.saphod.net/2008/10/17/firebug-and-the-mysterious-components-is-not-defined/

because I don't want to repeat myself here.

I hope this issue hasn't been posted before, if so I apologize for
posting it again - I haven't found it using the search.

Thanks!

Kind regards
Marco

Thanks - I started a new issue #1396:

Please include some information on why you think this is a Firebug
problem. Based on what you have posted here and the bug report, it
looks like a site error.

Please have a look at the website link provided and the comments.
I also posted an issue on the fbug site.

Thousands of bloggers are using WordPress, I think the code should be
valid.
Haven't had this problem in Firebug 1.2.1 (or similar - the one before
1.3.0).

Kind regards

Dear readers,

from here on, please refer to

Otherwise, I will have to double-post each time. :-)

Thanks!

The line with the error message is, according to your pages:
this.xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
It's not valid code, so it gives an error. Not a great message I
agree. But the error messages are given by Firefox, not by Firebug.

What do you see in Firefox > Tools > Error Console when you see the
message in Firebug? I guess the same message?

Hmmm....

On http://www.w3schools.com/php/php_ajax_xmlhttprequest.asp it says
that it is the way to make am AJAX request. The problem - as always -
is that there are 2 possible ways depending on which browser is being
used (FF or IE).

I must admit: I am having some trouble reproducing the error right
this instant - everything is fine. But that's what it was before. It's
hard that it just doesn't appear each time, that makes it harder to
track it down.

Maybe you are right. I can remember that issue being mentioned within
the Javascript console of Firefox, also - I guess. So, if Firebug only
reproduces the messages of the JavaScript console, then indeed it
shouldn't be a Firebug issue.

What amazes me is that I never had that issue before, it kind of
"suddenly" arose.

On my website post, a visitor made a comment that he changed the order
of this AJAX request within the createAJAX function of tw-sack.js to
first check for Firefox and then for IE, and that it helped preventing
the error.

I am still not convinced to believe that the problem lies within a
JavaScript code that is so heavily used. But maybe I will address the
author of that JavaScript.

Thanks jjb, I will try to keep you updated here.

Kind regards
Marco

I also started a Firefox issue in the mozilla forum:

From your post ::

"On my website post, a visitor made a comment that he changed the order
of this AJAX request within the createAJAX function of tw-sack.js to
first check for Firefox and then for IE, and that it helped preventing
the error."

That's because it was doing this "new ActiveXObject("Microsoft.XMLHTTP");"
which is NOT correct javascript that's why the error was happening - it has nothing do

with Firebug. This error would happen but you would never see it without Firebug
because Firefox will only show it in the error console.

The error is being generated by poor wordpress code. Open the bug with them and close the
bug in google code imo.

OK, on http://www.w3schools.com/php/php_ajax_xmlhttprequest.asp, it is
also recommended to first check for
Mozilla etc. and THEN for IE.

I'll contact the author of tw-sack.js again.

Still... what is meant by "Components"? And why does this error only
happen occasionally?

Well, as long as this is not clear to me, I'll leave the issue.
