Having the same issue. Please, please resolve this as soon as possible since a project I’m working on which needs this functionality goes live in a couple of days.
It works great except when trying to update it (however, it seems to adjust the amount of rows accordingly, just not setting its value), even though we’re using the field key. One tiny bit of error I snapped up was “Invalid argument supplied for foreach()” on line 1440 in api.php.
