Anyone else getting a webform error for a non-required date field?
Yes I get this when I add a Relationship on a webform and set Day and Month to be hidden.



I expect this needs to be done as an 'improvement' to the webform_civicrm code - you might want to open an issue at drupal.org/project/webform_civicrm but it will probably require some effort/funding to get it added
