Hi all,

 If I roslaunch webui, roslaunch my talker_listener.launch file manually, and then run the app in webui, it works, but if I just roslaunchwebui and try to run my app, the chatter topic is not subscribed to. Ifigure this is because the launch file isn't being executed. Is thisbecause I have my launch_file path set incorrectly?

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.
