Graphs do not show up and page load never finishes

[geld0r]

Hi,

I've tried to get this plugin running in an existing Vaadin application. I've followed the code examples and built a very simple LineChart. However upon loading the page that contains the graph, the actual graph never shows up. Instead I see that the loading bar is still present which never goes away.

I am using Vaadin 7.7.0 and the Gradle Vaadin Plugin in a Spring Boot application with vaadin-spring-boot.
In my build.gradle I only have compile "at.downdrown.vaadinaddons:highchartsapi:2.2.1-QF". As far as I understood, no additional setup should be required?

I initially thought that widgetset-compilation was required (which I never used so far - not really familiar with that). The Gradle Vaadin Plugin however should take care of that and it is not picking up any Widgetset.gwt.xml. The maintainer clarified, that this seems to be not required for this addon. Is this correct?

Edit: I just tried out the demo and am seeing the same issue. Is the add-on broken?
