CommState for Action Client #609
Description
I noticed the python action client library has a CommState that is used for determining when to call a done_cb function for goals. Currently the roslibjs action client goals end up on the GoalStatus PENDING status, which I can display in my UI, but it'd be nice to be able to display a done message (e.g., as axclient.py does). Is something that's easily implementable or has anyone tried this?
