gwt - mgwt attach CellSelectedHandler to GroupingCellList inside HeaderList

Question

I'm having trouble attaching an SelectionHandler to the contents of the mgwt HeaderList. How can I attach a CellSelectedHandler to a HeaderList just like in the Showcase? http://mobilegwt.appspot.com/showcase/#GroupedCellListPlace:

I already tryed to attach the Handler to the GrouingCellList with wich the HeaderList is built, but this Handler is never fired.

Anyone done this already?

我设法使用 SelectionHandler 而不是 GroupingCellList 上的 CellSelectedHandler 来获取 SelectEvents

        addHandlerRegistration(view.getList().addSelectionHandler(new SelectionHandler<Content>(){
        @Override
         public void onSelection(SelectionEvent<Content> event) {
                Window.alert("event"+event.getSelectedItem().getName());
        }
    }));
