[ros-users] Simple action client - querying its status

Just a quick question with regards to the simple action client - why is
using the getState() method considered improper when there is no goal
(action client outputs an ROS_ERROR when you do so). Is there another means
of querying the server to know whether it is currently handling a goal or

Or perhaps, am I mistaken in thinking that I should be needing to?
