我正在尝试使用“ComboBoxFilterRowHeaderComposite”实现 nattable。
过滤工作正常，但是当我尝试分组时过滤行后，它会引发以下异常

这是我的 ComboBoxFilterRowHeaderComposite 结构：
filterRowHeaderLayer = new ComboBoxFilterRowHeaderComposite<T>(
bodyLayerStack.getFilterList(),
bodyLayerStack.getGlazedListsEventLayer(), bodyLayerStack.getSortedList(),
columnAccessor, columnHeaderLayer, dataProvider, configRegistry);
在哪里，
columnAccessor = new ReflectiveColumnPropertyAccessor(propertyNames);
columnGroupHeaderLayer = new DynamicColumnGroupHeaderLayer(sortHeaderLayerStack, bodyLayerStack.getSelectionLayer(), bodyLayerStack.getColumnGroupModel(), tr);
DataProvider 是 com.vanguard.tip.epm.platform.ui.grid.next.DynamicColumnHeaderDataProvider；
在那之后
CornerLayerStack cornerLayerStack = new CornerLayerStack(rowHeaderLayerStack, filterRowHeaderLayer);
CompositeLayer gridLayer = new GridLayer(bodyLayerStack, filterRowHeaderLayer, rowHeaderLayerStack, cornerLayerStack);
然后在 GroupByHeaderLayer 中添加 gridLayer：
groupByHeaderLayer = new GroupByHeaderLayer(bodyLayerStack.getGroupByModel(), gridLayer, columnHeaderLayerStack.getDataProvider(),
new GroupByHeaderConfigurationWrapper(bodyLayerStack.getGroupByModel(), columnHeaderLayerStack.getDataProvider(), bodyLayerStack.getColumnGroupModel()));
CompositeLayer groupByComposite = new CompositeLayer(1, 2);
groupByComposite.setChildLayer(GroupByHeaderLayer.GROUP_BY_REGION, groupByHeaderLayer, 0, 0);
groupByComposite.setChildLayer("Grid", gridLayer, 0, 1);
我希望这能让您清楚地了解我对 Nattable 的使用。
当我使用具有相同结构的文本库过滤器时，分组工作正常：
filterStrategy = new DefaultGlazedListsFilterStrategy<T>(bodyLayerStack.getFilterList(), columnAccessor, configRegistry);
this.filterRowHeaderLayer = new FilterRowHeaderComposite<T>(filterStrategy, columnHeaderLayer, dataProvider, configRegistry);
