Sorting of list grid with unsaved edits

Hi,

I have a ListGrid where (some) rows are added using grid.startEditingNew.

Sorting of the unsaved rows does not seem to work.

Is this intended behaviour, or should sorting work for unsaved rows?

)I can produce a test case if sorting should work for rows added using startEditingNew.)

I´m using smartgwt 4.1p, 20140803

Regards
Rolf
