dynamic_reconfigure unable to (re)load dumped parameters [closed]

asked 2014-07-01 13:29:26 -0500

This happens when I dump and immediately try to load parameters for a node:

Hydro$rosrun dynamic_reconfigure dynparam dump /left_sa_camera_driver left_sa_camera_driver.yaml 
Hydro$rosrun dynamic_reconfigure dynparam load /left_sa_camera_driver left_sa_camera_driver.yaml 
error updating parameters: don't know parameter: groups
Hydro$

left_sa_camera_driver is a nodelet running in a nodelet manager together with other nodelets in this use-case. Otherwise, dynamic_reconfigure seems (largely) to work. I can change parameters via rqt_reconfigure, but some of them occasionally inexplicably oscillate between two different settings. Any hints on what might be the problem are appreciated.

Setup is Ubuntu 12.04/Hydro from .debs/AMD64

Why was this closed? This is still in 2019 a valid problem, whole 5 years later. Unbelievable that one can't dump a valid dynparam session and then load it again.
