Hi all,

I am trying to execute a state machine via an Action Service Wrapper. I would like to pass in userdata which has multiple fields. Here's how I would typically call the state machine:

sm = Navigate()
userdata = smach.UserData()
userdata.map_loc_name = map_loc_name

Here's how I'm currently using the ActionServerWrapper

asw = ActionServerWrapper(
    'navigation_state_machine', New, sm,
    ['did_something','did_something_else'], ['aborted'], ['preempted'],
    goal_key = 'map_loc_name',
    result_key = 'egad_its_a_result' )

I was wondering if anyone has suggestions on how I might pass in userdata.

After searching, I found this: which I believe answers my question. I will validate that this works on ROS Kinetic tomorrow.
