I'm trying to use the generator to build google-chart: https://github.com/GoogleWebComponents/google-chart

The error:

Hi, I've experienced the same issue when trying to compile the map component. It seems the generation is missing an import: import com.google.gwt.core.client.JsArray;

Notably, the JsArray import is included in other files.

The issue primarily seems to be if JsArray is only utilized as a RETURN value from a function and not used elsewhere.

I've found the issue in the templates used for generation. JsArray is imported in Widget.template: https://github.com/vaadin/gwt-api-generator/blob/master/template/Widget.template#l11

However, it's not imported in either ElementEvent.template or WidgetEvent.template
