note that i did register my drap and drop type in awakeFromNib, and
that code does get executed:
[outlineView registerForDraggedTypes:[NSArray
arrayWithObject:myAgendaNodeType]];
however, the following proc:
- (BOOL)outlineView:(NSOutlineView *)outlineView writeItems:(NSArray
*)items toPasteboard:(NSPasteboard *)pboard {
never gets called, which is why i suspect something is not set
properly in the nib.

i used the abstracttree sample project step by step instructions,

drop.
comparing the nib files between my implementation and the one that
comes in the sample code, i can't see anything different.
i do expect the drap and drop to require something setup properly in
the nib file for the outline view, but i just can't find it.
note that i did implement:
- (BOOL)outlineView:(NSOutlineView *)outlineView writeItems:(NSArray
*)items toPasteboard:(NSPasteboard *)pboard {
- (BOOL)outlineView:(NSOutlineView *)outlineView acceptDrop:(id
<NSDraggingInfo>)info item:(id)item childIndex:(NSInteger)index {
- (NSDragOperation)outlineView:(NSOutlineView *)outlineView
validateDrop:(id <NSDraggingInfo>)info proposedItem:(id)item
proposedChildIndex:(NSInteger)index {
what am i missing?
