cocoa -draggingImageComponents not called

Dear list,

I'm continuing my adventures in view-based tableview land. I've got drag-n-drop working nicely, but I'd like to improve the image that's shown during a drag. Currently I just get the subviews of my NSTableCellView subclass, but I don't get the background that's drawn in -drawBackgroundInRect: of my NSTableRowView subclass. The documentation seems to suggest that one should override -draggingImageComponents in the NSTableCellView subclass, but it seems never to be called.

Can anyone shed any light on this? Should I be overriding something in the NSTableRowView subclass instead? Is there a switch I need to flick to get -draggingImageComponents to be called?

Cheers,

Martin
