creation
------------------------+---------------------------------------------------
Reporter: clemens | Owner: faide
Type: defect | Status: new
Priority: normal | Milestone:
Component: TurboGears | Version: 1.9.x
Severity: normal | Keywords: catwalk sprox
------------------------+---------------------------------------------------
Action:
* new virtualenv --no-site-packages on Ubuntu 8.10
* cd tg_env; source bin/activate
* fresh install of tg-2.0b1 following
http://www.turbogears.org/2.0/docs/main/DownloadInstall.html
* paster quickstart demo # with auth
* cd demo
* paster setup-app development.ini
* paster serve development.ini
* browse to localhost:8080
* login
* browse to /admin
* select "Group"
* select "add"
* enter "newgroup" "newgroup" manager
* click "Submit"
Expected result:
* group "newgroup" added with member manager
Actual result:
InvalidRequestError: Invalid column expression '<function return_cls at
0xa06617c>'
Selecting permissions during group creation works fine if I don't also
select a User.
