How to bind a DateBox with Errai binding?

[calderas]

Hello,

I'm using Errai Binding according to (Data Binding - Errai - Project Documentation Editor).

Model >>

@Bindable

.. Empleado ..{

   ....

   Date fecha;

   .....

}

View>>

....

DateBox fechaDateBox;

....

dataBinder = DataBinder.forType(Empleado.class);

empleado = dataBinder

                .bind(fechaDateBox, "fecha")

                .getModel();

When I change the fechaDateBox, it throws an UmbrellaException.

I tried changing data-type String/Date, binding fechaDateBox.getTextBox(), .getDateTimePicker() and with a Convert.

DateBox implements HasValue.

So, which is the correct way to bind a DateBox with a Date property.

I'm using the SuperDev Mode. Into Developer Tools of Chrome, the UmbrellaException is throw by the class com.google.gwt.event.shared.HandlerManager line 127

....

// May throw an UmbrellaException.

eventBus.fireEvent(event);

...

UmbrellaException_5_g$ {cause_1_g$: UmbrellaException_5_g$, detailMessage_0_g$: "Exception caught: Exception caught: 01/01/2004", stackTrace_1_g$: null, __gwt$backingJsError: Error: Exception caught: Exception caught: 01/01/2004,causes_1_g$: HashSet_1_g$…}

1. __gwt$backingJsError: Error: Exception caught: Exception caught: 01/01/2004
2. cause_1_g$: UmbrellaException_5_g$
3. causes_1_g$: HashSet_1_g$
4. detailMessage_0_g$: "Exception caught: Exception caught: 01/01/2004"
5. stackTrace_1_g$: null
6. __proto__: Object

or

1. detailMessage_0_g$: "Exception caught: Exception caught: fecha"

Thanks.

Into the class org.jboss.errai.databinding.client.BindableProxyAgent

in the code:

....

      handlerRegistration = ((HasValue) widget).addValueChangeHandler(new ValueChangeHandler() {

        @Override

        public void onValueChange(ValueChangeEvent event) {

          Object oldValue = proxy.get(property);

          Object newValue = toModelValue(propertyTypes.get(property).getType(), widget, event.getValue(), converter);

          proxy.set(property, newValue);

          updateWidgetsAndFireEvent(property, oldValue, newValue, widget);

        }

....

this line: proxy.set(property, newValue); throws the NonExistingPropertyException for "fecha"

Thanks,

Hi,

This means that "fecha" is not a valid Java property or at least it wasn't recognized as one. Do you have getters/setters for it? Can you share your complete bindable/data type.

Cheers,

Problem/Solution found it.

Into .errai/BindableProxyLoaderImpl.java, Errai tries to override the getters/setters of the Model; however, the setter for fecha is final, so that blocks to override the setFecha method.

I had already removed the final but the gwt-incremental compilation is not enough to make effective the change into BindableProxyLoaderImpl. It was necessary to Clean/Build the full project; at least in NetBeans.

Thanks,

Juan
