Looking at my code.
It seems that I also had troubles getting this to work. I actually copied code from the GWT-tour project in my own project.
Also looking at the code I see this is using JSNI. If this is a new project, you probably want to avoid using JSNI in favor of JsInterop.
I could not found any JsInterop library for hopscotch, so best bet is to create it yourself, or look for another library which does the same thing. Or create your own pure GWT library doing this...
