Yii-User And Building A User List

Hi there,

I feel dumb but after hourse of searching and reading I need to ask around.
I'm not able to figure out how to build a list of users for a dropdownlist. I'm using yii-user (with yii-rights) and everything's working perfectly. I do use user profile's fields and user relations within other models, but I can't understand how to build such a dropdownlist.
What am I missing??

TIA,
rash*
