Bug 124238 Grid without data binding will throw npe and break report.
In GridItemExecutor the following line of code will throw npe if there is no result set: IResultIterator rsIterator = ( ( DteResultSet ) rset ).getResultIterator( ); Need a null check. This is very serious, it will break reports with grids that don't have data binding. I consider this a showstopper for the 2.0 release.

processVisibility( row, rowContent );
		IResultIterator rsIterator = ( ( DteResultSet ) rset )
				.getResultIterator( );
		IRowData rowData = null;
		if ( context.isInFactory( ) )
		{
			rowData = new RowData( rsIterator, TableItemExecutor
					.getValueExpressions( row ) );
			RowScriptExecutor.handleOnCreate( ( RowContent ) rowContent,
					rowData, context );
		}
		startTOCEntry( rowContent );
		if ( emitter != null )
		{
			emitter.startRow( rowContent );
		}
		for ( int j = 0; j < row.getCellCount( ); j++ )
		{
			CellDesign cell = row.getCell( j );
			if ( cell != null )
			{
				executeCell( rowContent, cell, emitter, rowData );
			}
		}
		if ( emitter != null )
		{
			emitter.endRow( rowContent );
		}
		finishTOCEntry( );
		context.popContent( );
