ComboBox我正在尝试重置如下的选择：

// private ListView<MyEntityType> f_lItems

f_lItems.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<Object>() {
    @Override
    public void changed(ObservableValue<?> ov, Object t, Object t1) {
        if (t1 != null && t1 instanceof MyEntityType) {

            MyEntityType pv = (MyEntityType) t1;
            // do some condition testing
            if (condition) {
                // accept 
            } else 
                // roll back to previous item
                f_lItems.getSelectionModel().select((MyEntityType) t);
            }
        }
    }
});

因此，在尝试将列表重置为旧值后，我收到此异常：
