help dragging from NSTableView to NSOutlineView, Core Data

I'm having difficulties obtaining the object(s) dragged from an NSTableView to an NSOutlineView when the drop happens.

Both views are in the same window. Both are controlled by separate Array and Tree Controllers. Drag and Drop inside the NSOutlineView is working fine. I see the drag initiating, and the acceptDrop is happening on the outlineview side. Just about all the right messages are getting passed, but when the drop happens on the Outline, the only thing that I can see I have access to in

- (BOOL)outlineView:(NSOutlineView *)outlineView acceptDrop:(id <NSDraggingInfo>)info item:(id)item childIndex:(int)index

is [info draggingSource]. This is the NSTable that is the source for the drag, but how do I ensure that the particular object being dragged is available?

I've implemented three methods for the table view in the datasource - both views use the same class as datasource:

- (BOOL)tableView:(NSTableView *)aTableView
			writeRowsWithIndexes:(NSIndexSet *)rowIndexes
			toPasteboard:(NSPasteboard*)pboard


and

- (NSDragOperation)tableView:(NSTableView*)tv validateDrop:(id <NSDraggingInfo>)info proposedRow:(int)row proposedDropOperation: (NSTableViewDropOperation)op

and

- (BOOL)tableView:(NSTableView *)aTableView
			acceptDrop:(id <NSDraggingInfo>)info
			row:(int)row
			dropOperation:(NSTableViewDropOperation)operation

and all of them are firing. The rowIndexes are archived and given to the pboard per an Apple example in tableView:writeRowsWithIndexes:toPasteboard: .

Sorry if this is obvious, but I haven't gotten there yet...
