[jira] [Created] (FLEX-33393) Support for nested xml data in datagrid datafield

Mikko Torniainen created FLEX-33393:
---------------------------------------

             Summary: 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


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.
