I have set row detail view property singleRowExpand: true, but now when I expand row and try to close it or try to expand another row everything is going undefined. this is happening after latest changes in slickgrid-universal I guess. its looking for index which does not exist in handleRemoveRow method (this.dataView.getItemByIdx() is returning undefined)

I tried reverting back to older slickgrid version it did not help.
