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?
