Hi Thomas,
Could you pls elaborate a bit. My code is as follows
Column<HotelSearchDTO, String> bookCol = new Column<HotelSearchDTO,
String>(new ButtonCell()) {
@Override
public String getValue(HotelSearchDTO object) {
return "Normal";
}
};
bookCol.setFieldUpdater(new FieldUpdater<HotelSearchDTO, String>() {
@Override
public void update(int index, HotelSearchDTO object, String value) {
// How to return "Loading..." from this place as this is the only place to
handle click event.
}
});
Thanks
Deepak
