>          Components: Spark: DataGrid
>    Affects Versions: Apache Flex 4.9.0
>            Reporter: Mikko Torniainen
>            Priority: Minor

> Quite often xml datasource isn't neatly in one level, but contains nested nodes. Spark datagrid partially supports using e4x-queries in gridcolumn-dataField, but it fails if you try to filter by an attribute (@) of a nested node. For convinience and consistancy this could also be supported.
> This works: @something
> This works: child
> This works: child.grandchild
> This does not work: child.(@id == 'something') and will also clear the headerText of that column for some reason.
> Workarounds:
>  - preprocess the xml to easier form before using it as dataprovider.
>  - extend the gridcolumn to pass custom data and use the labelfunction or itemrendererfunction instead.
