Tap4-4 contrib:table Error

[Joe Goldwasser <jo...@mjg2.com>]

Hi,
 
I just upgraded to the beta 4 of Tap4.  I am experiencing a new error when I
am submitting my form with a table in it.
 
The error is:

This seems to correspond to the line in the html for:
<input type="hidden" name="iterColumns"

Did something change with beta 4 that would require me to do something
different with the contrib table?
 
Thanks,
Joe
