rqt_reconfigure not displaying dynamic parameters
I am adding support of dynamic reconfigure to a node following this tutorial. ( http://wiki.ros.org/dynamic_reconfigure/Tutorials/SettingUpDynamicReconfigureForANode ). code is same as written in tutorial.
Problem: loading dynamic parameter in rqt_reconfigure gui
System Configuration : ROS Groovy on Ubuntu 12.04 LTS
Error : when selecting dynamic_reconfigure node in rqt_gui
