>    Affects Versions: Adobe Flex SDK Previous
>         Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Language Found: English
>            Reporter: Adobe JIRA
>             Fix For: Apache Flex 4.11.0

> Steps to reproduce:
> 1. Open AdvancedDataGrid.as
> 2. Scroll to line 3000 in function "override protected function drawRowBackgrounds():void"
> 3. implementation is "drawRowBackground(rowBGs, i++, rowInfo[curRow].y, rowInfo[curRow].height,
colors[d - 1], curRow);"
> 4. But the last argument "curRow" is not a dataIndex value;
>  
>  Actual Results:
>  
> Same as in DataGrid.as
> var actualRow:int = verticalScrollPosition;
>         var n:int = contentHolder.listItems.length;
>         while (curRow < n)
>         {
>             drawRowBackground(rowBGs, i++, contentHolder.rowInfo[curRow].y, contentHolder.rowInfo[curRow].height,

>                 colors[actualRow % colors.length], actualRow);
>             curRow++;
>             actualRow++;
>         }
> Where actualRow start index of verticalScrollPosition.
>  
>  Expected Results:
>  
> If verticalScrollPosition equals to 41 the dataIndex should equals to 41 as well not
to ZERO
>  
>  Workaround (if any):
>  
>  drawRowBackground(rowBGs, i++, rowInfo[curRow].y, rowInfo[curRow].height, colors[d -
1], actualRow);"
