Hi Thomas,
I did something like that,
boolean normalButtonClicked = false; // class variable
Column<HotelSearchDTO, String> bookCol = new Column<HotelSearchDTO,
> String>(new ButtonCell()) {
>
> @Override
> public String getValue(HotelSearchDTO object) {
> return normalButtonlicked ? "Loading…" : "Normal";;
>
}
> };
> bookCol.setFieldUpdater(new FieldUpdater<HotelSearchDTO, String>() {
>
> @Override
> public void update(int index, HotelSearchDTO object, String value) {
> normalButtonClicked = true;
>
// server operation
// on server completion { normalButtonClicked
= false;}
}
But its not working. The text of the button is never changed.
Regards
Deepak
