Redmine

Adding a member to a group via visting the groups user tab fails. No error message is shown via the webui, and error is logged in the server log. The error message is:

ActiveRecord::RecordInvalid (Validation failed: Project can't be blank):
app/models/group.rb:38:in `user_added'
app/models/group.rb:33:in `user_added'
app/controllers/groups_controller.rb:112:in `add_users'

Here is the path I took to reach this screen/error.

Administration -> Groups
Selecting a group
Choose Users Tab
Click check box next to users
Click add
