vaadin chart error : Widgetset does not contain implementation for com.vaad

Flow
1

Hi
I try to use a very simple chart


Chart chart = new Chart();
chart.setSizeFull();
//
Configuration conf = chart.getConfiguration();
conf.setTitle(“Chart”);
conf.getChart().setType(ChartType.LINE);
Random randomGenerator = new Random();
//
DataSeries dataprom = new DataSeries(“Promo”);
for(int i = 1; i < 10; i++ ) {
// Shoe size on the X-axis, age on the Y-axis
dataprom.add(new DataSeriesItem(
i,
randomGenerator.nextInt(10) ) );
}
conf.addSeries(dataprom);

but I get this error


Widgetset 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.

my aplication was initialy created with vaadin 7 and then migrated to vaadin 8
but I get that error with both chart version

vaadin 8


com.vaadin

this is the widgetSet I am using
(my aplication was initialy created with vaadin 7 and then migrated to vaadin 8)

@Widgetset(“com.vaadin.v7.Vaadin7WidgetSet”) // actual
public class MyAppUI extends UI {

Hi,
you should recompile the widgetset after adding chart dependecy.
Launch mvn clean vaadin:update-widgetset vaadin:compile and remove @Widgetset annotation from UI class; maven plugin will automatically generate a AppWidgetset that will be used by default by the UI.

See
https://vaadin.com/docs/v8/framework/addons/addons-maven.html
 and
https://vaadin.com/docs/v8/charts/java-api/charts-getting-started.html
 for further information.

Hi,
sorry for late response.
With Vaadin 8.x you should use charts 4.x.

Can you post the whole maven execution output? you may also add the -e flag (eg mvn -e vaadin:compile)

Creo que tengo el mismo error. Al usar jFreeChart se me genera un internal error. Las dependencias que agregue son :
