We have a Graphic view that not only summarizes plant operations, but allows the most commonly-used functions (start/stop etc.) to be controlled from that view. This has been operating just fine for a super-admin, but now that we've delegated the control to another user, it does not display the controls. It only displays an hourglass that never resolves to the expected input (binary toggle, numeric input).
The user has proper permissions, and is able to enter the input on the Data Points page without any problem. It's only on the Graphic view that this problem appears.
