Problems with rows marked as Removed in ListGrid

Hi

I have encountered problems when I want to mark rows as removed in a ListGrid.

1) The method markSelectionRemoved doesn't seem to work. When I select several rows and I call this method, only one row is marked as removed.
A workaround is to use the method markRecordRemoved which works fine.

2) I have another weird behavior if I initialize the ListGrid with setShowGridSummary(true).
- I mark one or several rows as removed
- I edit another row
- the "removed" rows are not marked as removed anymore
Any idea ?

I'm using :
- SmartGWT4.0
- GWT 2.5.1
