communication failed with #<TaskContext: Orocos::TaskContext//sonar_multibeam> (Orocos::CORBA::ComError)

[chyphen777]

When running ruby sonar_multibeam_rb I got several errors including communication failed, preceded by a warning (QApplication was not created in the main() thread). Not sure if they are related. Any suggestions how to fix those errors: Thanks. CC

When I switched the order of setup_task() and setup_widgets(), in sonar_multibeam.rb, the warning of "QApplication() not created" was gone, so was communication error. However I got stuck at different errors. Any suggestion how to track down and/or fix those errors.

Silly me. Task was not defined for setup-widegets after switching of code blocks. Now got other bugs to track. Close this issue.

Can you elaborate on how you solve this problem? Because I have similar problems, thank you very much

I got this error too. Could you explain better how you solved it?
