Maybe the chart has to be released as soon as the component is detached. Just guessing.

Seen at https://github.com/chartjs/Chart.js/blob/master/test/mockContext.js#L216

This might be a problem with chartjs itself. I ran into this exception while using ionic2 rc0. They fixed it in here: https://github.com/driftyco/ionic-app-scripts/pull/44

Keeps appearing after upgrade to Vaadin 8

What I think, gwt try to speak with server on ChartJsWidgetset-0.js, but there is no this widgetset
So, we need to compile our widgetset with it
Example widgetSet error:
https://github.com/parttio/Animator/issues/3
EDIT:
When I test problem via MyWidgetSet-0.js (custom), and all errors via Unknown.***(com.****.MyWidgetSet-0.js)
There is js file and methods, the problem on different think
