MoveIt joint_state_publisher not publishing to robot_state_publisher
I am working on a 7-DOF manipulator with MoveIt and have calculated a series of joint vectors. I want to publish these joint vectors to the joint states topic so as to see the visualization in Rviz. However, after the implementation I did see the visualization in Rviz but there were "jumping backs" to the original manipulator configuration from time to time. I went into the problem and found that the correct messages were being published to the joint states topic, but robot_state_publisher was not receiving these messages, so no new tfs were updated (the manipulator still stayed at the original configuration, I think this is why there were "jumping backs") .
As a test, I used the joint_state_publisher GUI to publish messages to the joint states topic and I did see tf updates from robot state publisher. So what I do not understand is why publishing using GUI results in new tfs but publishing using codes does not.
I checked and ensured there were joint_state_publisher and robot_state_publisher nodes running and robot_state_publisher node did subscribe to the joint states topic.
Any ideas would be greatly appreciated!
