Strange behaviour accessing textarea elements in IE

Hi all,

I've stumbled across some very weird behaviour in IE.

Basically if I try and get a handle to a hidden textarea in an
xforms:repeat  using getElementById() (and after I've dynamically inserted
a new element into the repeated set) the getElementById() function returns
the (first) newly inserted control not the hidden one I requested.

The attached file which will run in the sandbox *should* make this a little
clearer. It runs as expected in FF and Opera but not in IE 7.0 or 6.0

Can anyone provide an explanation for this behaviour?
I notice it only happens if I use xforms:textarea as xforms:input works ok.

Thanks,
Chris.

I am pretty sure that you are hitting this:

   http://www.csb7.com/test/ie_getelementbyid_bug/index.php

We implement in xforms.js a better version of getElementById() which
works around the problem:

   ORBEON.util.Dom.getElementById()

I replaced your calls to document.getElementById() with the above, and
it seems to work.

Don't you love IE and Microsoft?
