In the attached FeatureScreenShot.png, on selection of Lisa [3] - (3), we are getting selection object as Lisa[3] - (3), not the data inside the Lisa objects. As we need to do action on top of them, please suggest how to proceed int his case.

What answer do you expect on that question? There is almost no information despite the fact that something doesn't work as you expect.

Where do you get the IStructuredSelection from? Do you use our RowSelectionProvider? And if so, how?

We are using the RowSelectionProvider. On selection of groupbyobject, in its first line(i.e. heading), we are receiving only its header or heading. Not the internal objects in it. ILayer selection object shows only filter name. Is there any way to fetch internal objects in it. Or how to use filter object in GroupByModel class, so that I can give the filter name to fetch the group data.

Technically there is no real tree in a NatTable tree. It is a tree representation of a list. Therefore there is nothing like a direct "give me your children".

You can try to filter like we are doing it in the GroupByDataLayer for implementing the summary feature or try to ask the ITreeRowModel with the GroupByObject or its index in the TreeList to retrieve the children.

We were able to get this working by extending the existing RowSelectionProvider. When the current selection is a GroupByObject, we then make a call to GroupByDataLayer#getElementsInGroup to get the underlying rows. We then add those elements to the StructuredSelection.

I am willing to open up a feature request and contribute this code back to the project. I think it is something others might find useful. @Dirk, please let me know if you agree.
