Actually it probably is a problem with the webhandler or rosweb because the error is cannot subscribe to /chatter:more cannot subscribe to /chatter:split cannot subscribe to /chatter:split:2 cannot subscribe to /chatter:split:3 Thanks for the help, Max -----Original Message----- From: mwitt341 To: ros-users Sent: Fri, Jul 16, 2010 2:55 pm Subject: [ros-users] congifuring launch_file in webui apps If I roslaunch webui, roslaunch my talker_listener.launch file manually, and then run the app in webui it works, but if I just roslaunch webui and try to run my app, the chatter topic is not subscribed to. I figure this is because the launch file isn't being executed. It's probably because I have my launch_file path set wrongly. launch_file: sample_application/opt/ros/wu-ros-pkg/sample_application/talker_listener.launch the wiki details that this line should be the package_name/launch_file_path. Possibly relevant: when I roslaunch webui webui.launch and go to different pages in webui, the terminal prints warnings: [WARN] 1279308554.052159: Cannot subscribe to /texas_power/state [WARN] 1279308554.080325: Cannot subscribe to /dashboard_agg Thanks for the help.
