Attachment: Main.air
Main-app.xml
Main.mxml
> Support for nested xml data in datagrid datafield
> -------------------------------------------------
>
> Key: FLEX-33393
> URL: https://issues.apache.org/jira/browse/FLEX-33393
> Project: Apache Flex
> Issue Type: Improvement
> Components: Spark: DataGrid
> Affects Versions: Apache Flex 4.9.0
> Reporter: Mikko Torniainen
> Priority: Minor
> Labels: datafield, datagrid, e4x
> Attachments: Main.air, Main-app.xml, Main.mxml
>
>
> 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.
