How to reproduce
- Go to user management, search for a user
=> user found
- Go to admin->customizing->user properties
- Enable genericCheckboxProperty on the org.olat.admin.user.UsermanagerUserSearchForm context
- Go to user management and search for the same user again
=> NOK: user not found anymore (no matter wether checkbox is on or off)
Probably a left-join style problem. Fixable with reasonable effort?
