[ros-users] Non-simple action server?

[Vijay Pradeep]

Hi Tommy,

You are indeed correct in your understanding for the PREEMPTING->ABORTED and
PREEMPTING->SUCCEEDED transitions.  Even when a cancel request is received
from an ActionClient, it is possible for the user-code on the ActionServer
side to Succeed or Abort on the goal before ever noticing the cancel
request.
