no_button_action in CameraController of root camera not working

[KnightCoder]

I added a CameraController to the root camera however, when I try to set no_button_action to "Rotate Horizontal" it seems to crash the editor.

I noticed that it is throwing error "Uncaught TypeError: Cannot read property 'set' of undefined" in the update() function in the camera.js file.

Basically value of destination_eye in the following line of code is undefined camera._editor.destination_eye.set( camera.eye );

My intention of adding no_button_action is in the hope that it will rotate the scene on load when the user is not interacting with the scene. Also please tell me whether this understanding correct?
