When I open the project for part15 and try to run it, I get this set of errors:
Failed to load resource: net::ERR_EMPTY_RESPONSE (11:10:06:572 | error, network)
at http://localhost:8383/Part-015/js/libs/jquery-ui/ui/widget.js
Uncaught Error: Script error for: jqueryui-amd/widget

To fix it I had to
a) Go to project properties, and then to the list of bower packages, and then find and install jquery-ui-amd
b) edit main.js to change the require config to have
'jqueryui-amd': 'libs/jquery-ui-amd/jquery-ui-1.10.0/jqueryui/',
After that I could get on with what I was supposed to be doing.
Putting this here in case anyone else hits the same issue.
