As part of the design for Drupal Commons, users are able to create nodes inside of public groups in a single reference field, regardless of whether or not the user is already a member of the group.
OG provides separate "your groups" and "other groups" fields with separate autocomplete, validation and submission handling.
Can you advise on how we could use the OG/Entityreference API to provide these as a single field?
Switching the field to a basic Entityreference field causes OG to show the error,
[field] is a group-audience but its Entity selection mode is not defined as "Organic groups" in the field settings page
Additionally, I believe that some of the default validation from the og_group_ref field is useful, so my sense is we don't want to simply suppress that message and use a default entity reference field.
