They were using a session-scoped bean with concurrentDOMViews and setting the
list temporarily to null. We should check for null like so:

void populateItemList() {
        if (getSelectFacet() != null) {
            //facet being used on jsf page, so get the list from the value binding
            itemList = getListValue();
        } else {
            //selectItem or selectItems has been used on jsf page, so get the
selectItems
            itemList = Util.getSelectItems(FacesContext.getCurrentInstance(),
                                           this);
        }
        if( itemList != null ){
            Iterator items = itemList.iterator();
            SelectItem item = null;
            itemMap.clear();
            while (items.hasNext()) {
                item = (SelectItem) items.next();
                itemMap.put(item.getLabel(), item);
            }
        }
    }
