Bug 181706 Sorting Data by X values doesn't work without grouping
Using the 2.2M5 designer , I simply want to sort the data of the X Series in a Line Chart. I go into the Sort and Group pop up in the chart wizard and select ascending, but it doesn't affect the result. (style ordered same as the result set) If i define a dummy grouping (no interval) it is then working.

		else if ( cm instanceof ChartWithoutAxes )
		{
			ChartWithoutAxes cwoa = (ChartWithoutAxes) cm;
			sdBase = (SeriesDefinition) cwoa.getSeriesDefinitions( ).get( 0 );
			bBaseGrouping = rsw.getRowCount( ) > 0
					&& sdBase.getGrouping( ) != null
					&& sdBase.getGrouping( ).isEnabled( );
			
			aggHelper.addSeriesDefinitions( sdBase.getSeriesDefinitions( ),
					lhmLookup );
		}
		if ( bBaseGrouping
				&& aggHelper.getDataDefinitionsForBaseGrouping( ).size( ) > 0 )
		{
			
			aggHelper.addAggregation( sdBase.getGrouping( )
					.getAggregateExpression( ),
					aggHelper.getDataDefinitionsForBaseGrouping( ) );
		}
		
		if ( !aggHelper.isEmpty( ) )
		{
			rsw.applyBaseSeriesSortingAndGrouping( sdBase,
					aggHelper.getAggregations( ),
					aggHelper.getDataDefinitions( ) );
		}
		aggHelper.dispose( );
		return rsw;
