I do not see why this would be needed.  Inheriting from ATWorkgroup
means you also inherit the actions from ATWorkgroup. :)

vocbulary_factory should be vocabulary_factory

>>     schema["description"].widget.visible = {"edit":"hidden",

>>     schema["vendorID"].widget.visible = {"edit":"visible",

Also, the schema should be edited outside of the class definition.

I cannot imagine that these proposed changes fix your problem, but I
spot no other glaring errors.
