Hi Tully,

The problem was that I wasn't naming my topic /foo_array. I had
incorrectly assumed that rviz would detect from the type of the topic
whether to subscribe to it as Marker or MarkerArray. Subscribing to /foo
in rviz while publishing to /foo_array in my ROS node works correctly
(although I find it a bit counterintuitive). Thanks for your help!

Hi Ross,
I'm glad it working for you.

Indeed it is a little counterintuitive. I've filed a ticket here https://code.ros.org/trac/ros-pkg/ticket/4672
