---------------------------------------
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.
