Hello,

I've been working a fair bit lately on a project that uses ajaxCFC,
and I have just come across a strange bug that I was hoping someone
may be able to shed some light on. I have a page where the main
scripts that make up the JS side of ajaxCFC are present, when a user
clicks on a element on the page, ajaxCFC is used to send form data to
the server, nothing really unusual. And it all works just beautifully
in Firefox.

But in IE7 when the page loads, I get one of those unhelpful error
messages from IE that tells me:

Line: 9
Char: 3
Error: 'null' is null or not an object
Code: 0
URL: <the page I'm looking at>

It seems that the issue may have something to do with util.js, which
is part of ajaxCFC, if I comment out the line that includes util.js,
then the error goes away but is replaced with another error
complaining that DWRUtil is undefined, due to this object being in the
file I just commented out and this object being needed to serialize
the form data to be sent.

So I guess my questions are:

1: Can anybody tell me how to interpret this crappy error output from
IE? Within which file should I be looking at line 9? As it's not the
HTML page I'm looking at that's for sure. Looking at line 9 in util.js
shows me a comment line, not code...

2. Has anyone come across a any similar "'null' is null or not an
object" errors with a JS script that works just fine in Firefox but
gives this error in IE7?

Any help much appreciated as always.
