「ComboBoxFilterRowHeaderComposite」で nattable を実装しようとしています。
フィルタリングは正常に機能していますが、グループ化しようとすると行をフィルタリングした後、次の例外がスローされます
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

ComboBoxFilterRowHeaderComposite の構造は次のとおりです。
filterRowHeaderLayer = new ComboBoxFilterRowHeaderComposite<T>(
bodyLayerStack.getFilterList(),
bodyLayerStack.getGlazedListsEventLayer(), bodyLayerStack.getSortedList(),
columnAccessor, columnHeaderLayer, dataProvider, configRegistry);
どこ、
columnAccessor = new ReflectiveColumnPropertyAccessor(propertyNames);
columnGroupHeaderLayer = new DynamicColumnGroupHeaderLayer(sortHeaderLayerStack, bodyLayerStack.getSelectionLayer(), bodyLayerStack.getColumnGroupModel(), tr);
DataProvider は com.vanguard.tip.epm.platform.ui.grid.next.DynamicColumnHeaderDataProvider です。
その後
CornerLayerStack cornerLayerStack = new CornerLayerStack(rowHeaderLayerStack, filterRowHeaderLayer);
CompositeLayer gridLayer = new GridLayer(bodyLayerStack, filterRowHeaderLayer, rowHeaderLayerStack, cornerLayerStack);
次に、GroupByHeaderLayer に gridLayer を追加します。
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);
これにより、私の Nattable の使用法が明確になることを願っています。
同じ構造のテキストベースフィルターを使用すると、グループ化は正常に機能します:
filterStrategy = new DefaultGlazedListsFilterStrategy<T>(bodyLayerStack.getFilterList(), columnAccessor, configRegistry);
this.filterRowHeaderLayer = new FilterRowHeaderComposite<T>(filterStrategy, columnHeaderLayer, dataProvider, configRegistry);
さらに情報が必要な場合はお知らせください。
