I checked FAQ but none of the 2 solutions described applies to my problem. Name and id value remains the same and there are no dynamically inserted elements on that page.
Perhaps you could try to reproduce my process and see if you could come up with the solution? ID's that are left behind blank are the following 2:
<input name="contact_text_ok" id="contact_text_ok" type="checkbox" tabindex="1" value="1">
<input tabindex="1" id="xstreet0" class="nreq" name="xstreet0" size="20" maxlength="80" value="">
Thanks!
