6 years ago okey, so the problem has been found.
All the web resources has been moved from http://cdn.robotwebtools.org/ to http://static.robotwebtools.org/.
However, it is not able to show the robot model now. Very strange.
In case if it may help; here is the changed file with working urls:

Hello,
I am having problem with implementation of chapter 12. No models are being displayed once the submit button is clicked.
I have tried to debug the problem and found that none of the webtools api is working:
Is there a way across it??
Many Thanks.
