[FLEX-33248] Spark GridItemEditor cannot edit nested properties

• Type: Bug
• Status: Reopened
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: Apache Flex 4.8 (parity release)
• Fix Version/s: Apache Flex Next, Apache Flex 4.10.0
• Component/s: Spark: DataGrid
• Assignee: Carol Frampton

Description

To reproduce:

<s:DataGrid editable="true">
<s:columns>
<s:ArrayList>
<s:GridColumn dataField="someProperty.nestedProperty" />
</s:ArrayList>
</s:columns>
</s:DataGrid>

This will throw a "no such property" error when the user tries to edit a cell, because GridItemEditor tries to access `_data[column.dataField]` in the `data` setter.
I filed it as a bug and not as an improvement, because it is inconsistent with `GridItemRenderer`'s behaviour, which does render the nested property correctly.

Note that the `save()` method is also affected: the item's property is accessed in the same way there.
