Completing a poll, visiting the poll again with checksum generates an error

[slamorte]

I have a poll I set up for our union membership. Members receive a Mailing with a CiviPetition link with checksum and cid that auto-fills their contact profile for them. Then they can answer and submit the poll. All good so far.

But if they visit the poll a second time via the checksum link they get the "You have already signed this petition" screen and a big screen-full of red errors:

Code: [Select]

    Notice: Undefined offset: 53 in CRM_Core_BAO_UFGroup::setProfileDefaults() (line 2260 of /home/members/rutgersaaupaft/sites/rutgersaaup.org/web/sites/all/modules/civicrm/CRM/Core/BAO/UFGroup.php).

Removing the checksum allows them to revisit the poll's "You have already signed this petition" page without the errors.

Notice errors are undesirable because they suggest the code could be improved but do not necessarily indicate a problem - you should ensure notice errors are not displayed on production sites -I think you are on drupal so something like this might help

Thanks Eileen. I turned errors off.
