AMChart and Vaadin

Hello everyone,

We would use an AmChart on our Vaadin Application.
We get difficulties to implements that, we import amchart’s javascript, but when we try to add our AmChart component on vaddin Component we get this message :

Widgetset does not contain implementation for Check its @ClientWidget 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. Unrendered UIDL:

After looking on differents topics we never find someone who used other librairies than Vaadin charts add-on (highchart, vaadin-charts, …) Did someone work with other chartJS lib? How did you implement that (client side, and widegset)
