Hi,
If all children that pertain to a given group already share the same parent
(parentKey) that means the group is kind of already here, it is just that it
is not exposed to Flex in manner that please it.
Indeed HierarchicalData does not work out its hierarchy from parent
relationship (parentKey-key) as you have but from children relationship
(childrenField).
So you need to expose the relationship that way instead of the other way around.
Either you have the ability to change your data to expose them that way which
would be the simplest, or you have to find a workaround. Maybe using
groupingObjectFunction on your grouping to return the instance of the parent
(the one pointed by parentKey) would help? (not tested though)
Hope this helps,

I have a flat data array with the field key and parentKey
I am using a GroupedCollection in a ADG.
I have set the GC groupingField to be parentKey
This group everything by parenKey in a simple fashion but there doesnt
seem to be a way to connect parentKey and key together so that it nests
the rows correctly.
ie the item with key==1 should have nested children that have
parentKey==1
How do I do this?
