Hiding objects problem

[Gabba]

Hi guys, it's just me or it's something like a bug? If I try to hide an object under SAP I get this error:

' ERROR : Tipo non corrispondente: 'fr_visible' - [line 149 in C:\Program Files\Autodesk\Softimage 2011 Subscription Advantage Pack\Application\DSScripts\layers.vbs]
ToggleVisibility

Any suggestion?

Hi guys, seemd that I solved the problem. Even if I didn't opened the face robot interface, and in the specific tab it was disabled, enabling and then disabling face robot, worked for solving the problem.
