I am trying to run the sample HTML page given in Bosch's remote_lab/rosjs_tutorials package to create an actionlib client in Javascript (tutorial_actionlib.html). The client can connect to rosbridge, connect to the action server, but fails when sending the action. Here is the output given from the client:

Connecting to rosbridge.
Connection to rosbridge established.
Waiting for fibonacci action server to come online.
Sending goal to action server.
Waiting for results from action server.
Didn't receive results from action server.

It looks as if something is going wrong on the rosbridge side of things. Here is the output:

subscribing to: /fibonacci/status
subscribing to: /fibonacci/result
subscribing to: /fibonacci/feedback

I am running the current experimental SVN build of rosbridge (needed to work on Fuerte) on Ubuntu 12.04 using ROS Fuerte. I know that there were some problems with rostime and Fuerte a few weeks ago and did not know enough about the inner workings of rosbridge to know if this was related or a different problem. Any thoughts are greatly appreciated!

Thanks for the response! Unfortunately, I am actually using the version of rosbridge with the fix stated in that post (I actually linked to the same post in my original question :) ). Still investigating!

I just tried to duplicate this problem and was unable to. I am using revision 2891. Which version are you running?

2891 as well... turns out there was a local modification that I was unaware of. Sorry for the waste of time :)
