I have made a plugin which displays media manager for backend admins with different permissions, it works fine when I access the backend with admin with full permissions but when I access the backend with restricted users permissions I get the following error:

A widget with class name 'ocmediamanager' has not been bound to the controller" on line 513 of /modules/backend/Classes/Controller.php

I searched the net for any hint about this error but I didn't find.

I'm using October CMS Build: 434

Please Advice,

We had this error as well, and found that the restricted admin needs permission for Media for being able to insert media using the editor as using in the Pages plugin.
