Rights With Yii-User-Management

Welcome everyone,

I’d like to set up yii-user-management module with rights module. I have installed rights modules, and it is working, I installed yum module and it is also working. I generated all operations for yum module in rights interface. Everything seems to be ok, roles are assigned to users.

but when i go to roles ,taska and operation menu its error CException

Property "YumWebUser.rightsReturnUrl" is not defined.
