Use of pseudo-tag in hierarchical selector causes exception

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Take one of the IE7-JS test pages, such as
http://ie7-js.googlecode.com/svn/test/child.html
2. Add the following CSS to the style section:

#test a:hover
{
    background-position: 0px -123px;
}

3. Open the page in IE6.

What is the expected output? What do you see instead?
As these is no body element with the id 'test', nothing should be seen.
However, there should also be no issue in loading the page.

Instead, a JavaScript exception is thrown. Debugging results in the
following problem being highlighted:

Line 529:
var _selectorFunction=function(e0,s){IE7._indexed++;var
r=[],p={},reg=[],d=document;var
e1=IE7._byId(d,'test');if(e1&&e0==d||e0.contains(e1)){var
p2=0,i2,e2,n2=e1.getElementsByTagName('A');for(i2=0;(e2=n2[i2]);i2++){r[r.length
]=e2;if(s)return
e2;}}return s?null:r}

Object doesn't support this property or method on:
if(e1&&e0==d||e0.contains(e1))

What version of the product are you using? On what operating system?
2.0(beta) of IE7-JS, on IE6.0.2900, on Windows XP.

> if(e1&&e0==d||e0.contains(e1))

I can see the problem. Will fix for the next release.

This bug is pretty much a dealbreaker for our site, removing all teh :hover and
:before isn't much of an option. Really excited to try out the next release 
though :)

We're currently experiencing an exception on the same line of code. You've 
probably
grown tired of answering this question but is there any note on when the next 
release
is due Dean? We're currently using your IE7 js for our bachelor degree 
assignment,
and we'd really appreciate it if we were to know if we're able to count on a 
next
release that'll fix this bug in time (which is pretty much around the end of 
this week).

Thanks in advance, and keep up the good work!

I'll issue a new release sometime in the next few days. I can't make a release 
every
time a fix a bug so there will be at least a two week delay between releases. 
That
said, I've fixed a few bugs since beta 1 and will release beta 2 shortly.

I could run this project much like I run base2. In base2 I have a "live" 
directory
which contains the most up-to-date version of the library. Shall I do the same 
for IE7?

OK. The dev area is:

http://ie7-js.googlecode.com/svn/trunk/lib/

You can link to the source files there for the latest development version. 
Currently
though it is still the beta 1 version. I will update it as soon as I have time 
to
perform some basic testing.

Hi Dean, again, thanks for the fast response Dean and for allowing us to access 
your
version control trunk!

Hello Dean, great work and I'm waiting for new bug-fix release too :).

Hi Dean,
thanks a lot for your improved IE7 and IE8 scripts.
I was about to start writing one myself, to fix the couple most annoying bugs 
in IE7
(the actual browser) when I noticed you had posted your new versions!

I'm also holding my breath for Google Code revision 20, as this hierarchical 
selector
bug is a show-stopper for me.
