My (dirty) workaround was extending AbstractCell class and adding the
custom code within:
@Override
public void onBrowserEvent(final Context context, final Element parent,
final C value,
final NativeEvent event, final ValueUpdater<C>
valueUpdater) {
HasData<T> data = this.column.getTable();
SelectionModel<? super T> selectionModel =
data.getSelectionModel();
if (selectionModel instanceof SingleSelectionModel) {
T val = (T) ((SingleSelectionModel<? super T>)
selectionModel).getSelectedObject();
userChoiceHandler.onUserChoice(val);
}
}
method.
btw, has anyone an idea why the method getSelectionModel() from HasData<T>
class returns
SelectionModel<? super T>
instead of
SelectionModel<T>
?
