I've reviewed this issue again and found that the invitee did register with the email address that was used for the invitation and although the invite was accepted, they were never placed in the group. No group user row with the user_id column set to 0 exists.
I set up a test environment for further testing hoping to identify an issue with our setup, but have gotten the same results.
The test environment is setup according to:
• CB 2.0 Tutorials 1 - 5 & 22 (Integration with Kunena)
• GroupJive 3.0 Tutorials 1 & 2
• Admin Approval not required for registration
• The test environment is at
www.coolstrudel.com
Here's a summary of the test results:
Group member invites non-site user using group invites (Invitee status is pending)
Invitee receives email and clicks on email group link; invitee is taken to site with Group Users Tab displayed (no option to join); (Invitee status still pending on senders group invites)
After the Invitee clicks the sign up link and registers with invite email address - the senders group invite status displays Accepted; (invitee not yet in group)
Invitee receives confirmation email: "Your sign up request is pending approval;" invitee clicks on email confirmation link and is taken to site displaying "Your account is now active. You may now log in!;" (Invitee also receives "Sign Up" email approving application)
Invitee logs in using registration username and password and is taken to their profile where the Groups-Tab displays "You have no groups." (the non-site user has not been added to the invited group).
I appreciate your reviewing this and helping us resolve this issue.
