     * view). Only applies to databound listGrids where the {@link com.smartgwt.client.widgets.grid.ListGrid#getData data}
     * attribute is a {@link com.smartgwt.client.data.ResultSet}. This ResultSet may have been created manually and applied to
     * the grid via a call to {@link com.smartgwt.client.widgets.grid.ListGrid#setData setData()} or may have been created and
     * automatically assigned if {@link com.smartgwt.client.widgets.grid.ListGrid#fetchData fetchData()} was used to populate
     * the grid. This method is fired directly in response to {@link com.smartgwt.client.data.ResultSet#addDataArrivedHandler
     * dataArrived()} firing on the data object. <P> Note that <code>dataArrived()</code>, unlike {@link
     * com.smartgwt.client.widgets.grid.ListGrid#addDataChangedHandler ListGrid.dataChanged()}, only fires in limited
     * circumstances - when data for a {@link com.smartgwt.client.data.ResultSet} arrives from the DataSource due to a fetch or
     * cache invalidation, or as a result of {@link com.smartgwt.client.widgets.grid.ListGrid#getFilterLocalData filtering}. 
     * If you want to catch all data changes, you should instead react to {@link
     * com.smartgwt.client.widgets.grid.ListGrid#addDataChangedHandler ListGrid.dataChanged()}.
