We have created one shared briefcase using wiki account.

One of the user with admin rights try to share one of the subfolder under Main folder to others using his own credential.

Main folder (created and shared using wiki account)
-subfolder (created and shared by user)

When others user received the shared notification email, the subject showed "Shared created: subfolder shared by undefined". Once clicked on accept share, it will showed "invalid request: invalid long value 'undefined' for attribute: rid

The user only can accept the shared for the subfolder when we resend the shared notification from the wiki account.

How can we solved this or was this a bug? Thank you for advice.
