I have implemented sort thorough command handler.
The default sort configuration has been appiled.

My NatTabel has mor than 25+rows.

Sorting works for intial 8 rows but after that ,the sort handler crashes :

Not sure what you are doing, but at position -1 can't be a comparator in any list in Java

While analysing the issue observed that in doCommand for SortCommand

[i]final int columnIndex = command.getLayer().getColumnIndexByPosition(command.getColumnPosition());[/i]

columnIndex is coming as -1 for ceartain columns.

I have column grouping as well.Could that be causing some issue.

I have added default Sort ConfigurationcoverSheetNatTable.addConfiguration(new DefaultSortConfiguration());

Created sortModel
sortModel = new GlazedListsSortModel(getSortedList(), columnPropertyAccessor, configRegistry, columnGroupHeaderLayer);
this.sortHeaderLayer = new SortHeaderLayer(columnGroupHeaderLayer,
sortModel, false)

I am implementing the sort through command ,which is available on column header

public void registerSortCommandHandler(final ISortModel sortModel, final SortHeaderLayer sortHeaderLayer)
{
registerCommandHandler(new SortCommandHandler(sortModel,sortHeaderLayer)
}

Added menu item for sort

public void addMenuItem(final NatTable natTable, final Menu popUpMenu)
{

MenuItem multiEditMenuItem = new MenuItem(popUpMenu, SWT.NONE);
multiEditMenuItem.setText("Sort\t");


multiEditMenuItem.addListener(SWT.Selection, new Listener() {

@Override
public void handleEvent(Event arg0)
{
// natTable.doCommand(new TCNatTablePasteDataCommand("\t", System
// .getProperty("line.separator")));
NatEventData obj = (NatEventData) popUpMenu.getData();
final int colIndex = natTable.getColumnIndexByPosition(obj.getColumnPosition());
natTable.doCommand(new SortColumnCommand(natTable,colIndex,false));

//natTable.refresh();

}

The issue is that you are doing the position - index transformation before executing the command. You need to simply use the position as the transformation is done on command transport

Thanks ,for the input,now I modified my code as :

final int colIndex = obj.getColumnPosition();

The crash is getting avoided.I can see sorting working for most of the columns.
Following are issue which I still observe:

1. On applying the sort for particular column through sort command.I
do not see the cell painter(arrow) getting applied on the column header ,instead I see it applied on previous column's header.

2. In my tabel there are column group and on applying the sort on columns which appear after the column group does not show the sort cell painter.

Sounds like you registered the painters to the wrong layers or have some issues in your layer compositions.

Please check the various integration examples for verification.
