This is the same issue listed here but my understanding of the issue has changed enough that it really isn't the same question anymore. (If any mods disagree I'm happy to take guidance on this point.) I am using the CiviCRM Webform Integration module in Drupal 7 to have users register both themselves and their children for events. Currently, they are not able to see their children even though their relationships are permissioned in CiviCRM. I believe the issue is that my ACL permissioned relationships are broken.
I'm using CivCRM 4.6.18, Related Permissions 1.1, Drupal 7.43, Webform 7.x-4.12, and Webform Civicrm Integration 7.x-4.15+27-dev
Any clues appreciated, even if you don't' have a complete answer!
