Drag between 2 NSTableView?

Subject: Drag between 2 NSTableView?

I am trying setup drag & drop between two NSTableViews. I am getting - (NSDragOperation)draggingEntered:(id <NSDraggingInfo>)sender calls when the mouse enters the destination NSTableView. But I am not sure how I would figure out which row they dropped on. Both NSTableViews are bound to array controllers.

Also, I thought that the destination NSTableView would call:

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

- or -

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

but it does not.

Am I missing something here. I could not find any archived messages for this.

I tried subclassing NSTableView and override:

- (NSDragOperation)draggingSourceOperationMaskForLocal:(BOOL)isLocal
{
    return NSDragOperationCopy;
}

but it does not help.

Thanks,
