Row Selection [message #988775]

This is probably a simple problem but my NatTable is not highlighting selected row when I click on the row header. I also want to enable multi-row selection. What am I missing.

How did you instantiate the SelectionLayer? It sounds like an issue with the row header layer dependency.

I am creating my own GlazedList where each row is a HistoryItem:

EventList<HistoryItem> eventList = GlazedLists.eventList(model.getHistoryList());
FilterList<HistoryItem> filterList = new FilterList<HistoryItem>(eventList);
SortedList<HistoryItem> sortedList = new SortedList<HistoryItem> (filterList, null);

IColumnPropertyAccessor<HistoryItem> columnPropertyAccessor = new
ReflectiveColumnPropertyAccessor<HistoryItem>(propertyNames);

ListDataProvider<HistoryItem> bodyDataProvider = new ListDataProvider<HistoryItem>
(sortedList, columnPropertyAccessor);
DataLayer bodyDataLayer = new DataLayer(bodyDataProvider);
GlazedListsEventLayer<HistoryItem> glazedListsEventLayer = new
GlazedListsEventLayer<HistoryItem>(bodyDataLayer, eventList);
DefaultBodyLayerStack bodyLayerStack = new
DefaultBodyLayerStack(glazedListsEventLayer);
SelectionLayer selectionLayer = bodyLayerStack.getSelectionLayer();

...
Here is my RowHeaderLayer:
IDataProvider rowHeaderDataProvider = new
DefaultRowHeaderDataProvider(bodyDataProvider);
IUniqueIndexLayer rowHeaderDataLayer = new
DefaultRowHeaderDataLayer(rowHeaderDataProvider);
RowHeaderLayer rowHeaderLayer = new RowHeaderLayer(rowHeaderDataLayer,
bodyDataLayer, selectionLayer);

Thanks for your help,

Well this looks reasonable. At least the parts you posted. If it doesn't work, than maybe you forgot to link your layers correctly to the GridLayer you are using?

Have a look at the DefaultGridLayer. There the init method does the similar thing you are trying to do. Maybe it is just a typo in setting the references.

Thanks for the reply. I finally had to start over and got it to work. I guess I had a bad reference as you suggested.
