I am trying to run octomap_server along with hector_indoor_slam. But when I try to map, I get an error with octomap as follows,

[ERROR] [1442979646.410189416, 1543.345000000]: Client [/rviz] wants topic /octomap_point_cloud_centers to have datatype/md5sum [nav_msgs/OccupancyGrid/3381f2d731d4076ec5c71b0759edbe4e], but our version has [sensor_msgs/PointCloud2/1158d486dd51d683ce2f1be655c3c181]. Dropping connection.

The error message indicates there is a mismatch of message types between the publisher and subscriber sides. It looks like you accidentally tried using a "OccupancyGrid" display for the /octomap_point_cloud_centerstopic. This is wrong however, you should be using a "PointCloud2" display for that topic.
