Hi, i am trying to record with rosbag the content of a topic from moveit in order to planning a trajectory for an abb robot, specifically a trajectory goal. When i look what is inside the topic there are a lot of messages, velocity, position... But when i record the topic and get the info from the bag it only records one message, i am beginner in ros so i don't know if it is normal. I read the tutorials and rosbag record is supposed to store all the content of the topic is it not?With other topics it stores me a normal message number. The topic is /joint_trajectory_action/goal.

A FollowJointTrajectory goal consists of only a single message, so if you've only sent a single goal to the driver (ie: planned a single motion and executed it), then it would seem expected you find only a single message on /joint_trajectory_action/goal.
