Gear joints in Corona

Latest corona documentation says that it supports Gear joints. http://docs.coronalabs.com/api/library/physics/newJoint.html. For some reason I am not able to get the arguments right. The compiler complains if the method is given an object as second argument and asks for a joint. Sending joints as second and third argument also cause a compiler error. Has anyone been able to implement gear joint successfully? I am using SDK version 971. [import]uid: 221265 topic_id: 36155 reply_id: 336155[/import]
