It seems that in GXT2.0 M2 the SelectionChanged Event is fired on a component even if the selected Item has not been changed.

To see this behavior select an Item in a GRID, then select the same item in the GRID, the selectionChanged event will fire on both selection. In the past it would only fire when the selection was changed.

Is this a bug in GXT2.0 or has the event model changed ?
