Hi I noticed that the Python API of dynamic_reconfigure has somewhat changed from Electric to Fuerte, but there is no documentation or mention of those changes on the homepage or wiki or anywhere else actually. I reported some experience with it, that I encountered when fixing the sick_ldmrs driver: http://answers.ros.org/question/36526/dynamic_reconfigure-python-changes-in-fuerte/ the patch to the sick_ldmrs driver has been submitted to their maintainer (CSIRO), although they told me that they don't work on it much nowadays. I am reporting the problem here again, in the hope that someone in charge of dynamic_reconfigure could take a look. Regards Brice
