Hi, I use springboot2.0 and vaadin 8.3.1 and get :
Widgetset ‘com.vaadin.DefaultWidgetSet’ does not contain implementation for com.vaadin.addon.charts.Chart. Check its component connector’s @Connect mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions.

I checked /main/java/AppWidgetset.gwt.xml,

<inherits name="com.vaadin.DefaultWidgetSet" />

Any Idea?
