NSOutlineView + NSTreeController + Drag & Drop

Hi,

I am using Cocoa bindings on a NSOutlineView using a NSTreeController which works alright. Now I want to add a data source to support drag & drop on that outline view. Sadly, this does not work and I get the following exception:

*** Illegal NSOutlineView data source (<METreeController: 0x3a0620> [entity: Activity]). Must implement outlineView:numberOfChildrenOfItem:, outlineView:isItemExpandable:, outlineView:child:ofItem: and outlineView:objectValueForTableColumn:byItem:

It seems as NSOutlineView does not know about the tree controller and expects a classical data source.

When I use the same setup with a NSTableView and an NSArrayController, I am able to supply a data source that only delivers delegate methods for drag & drop.

Has anybody solved this problem yet or is this a bug in Cocoa?

Cheers

 Frank
