Example 2 with ValidationException

use of com.vaadin.data.ValidationException in project charts by vaadin.

the class ChartWithExternalDataProviderWithChangingData method getChart.

@Override
protected Component getChart() {
    HorizontalLayout lo = new HorizontalLayout();
    VerticalLayout vlo = new VerticalLayout();
    DataProviderSeries<Data> ds = createChartDS();
    Component grid = createGrid();
    TextField field = new TextField("New data value");
    Binder<Data> binder = new Binder<>();
    binder.forField(field).withValidator((String v) -> v != null && !v.isEmpty(), "The field cannot be empty").withConverter(new StringToDoubleConverter("Not a double")).bind(Data::getValue, Data::setValue);
    binder.readBean(new Data(0.0));
    Button button = new Button("Add data", e -> {

        } catch (ValidationException ve) {
        }
    });
    Component chart = createChart(ds);
    vlo.addComponents(field, button, grid);
    vlo.setSpacing(true);
    lo.addComponents(vlo, chart);
    grid.setSizeFull();
