i have make modification on this code. If you make selection, and aplys a filter on the store and reload it, the selection model have a first empty array in this selected collection ( at index 0 ).

This modification is in the last line of the "refreshSelection" function.

if (newRecordsToSelect.length >= 1){
        this.getSelectionModel().select(newRecordsToSelect);
        Ext.defer(this.setScrollTop, 30, this, [this.getView().scrollState.top]);
    }
