CheckComboBox documentation's bad example

Issue #830 new

created an issue

In the documentation of CheckComboBox the, otherwise helpful, example is written:

// and listen to the relevant events (e.g. when the selected indices or 
 // selected items change).
 checkComboBox.getCheckModel().getCheckedItems().addListener(new ListChangeListener<String>() {
     public void onChanged(ListChangeListener.Change<? extends String> c) {

The problem here is that getSelectedItems() is not a method.

The correct method is getCheckedItems().

I bring it up because it could prove blocking to new users.

It surely took me a not-so-quick minute to figure it out.

    It might be helpful to add a simple

    while( {
        //do something with changes here

    because according to the documentation of ListChangeListener,

    Important: It's necessary to call next() method before calling any other method of Change. The same applies after calling reset(). The only methods that works at any time is getList().
