Its working fine on Leopard.
The behavior was indeed changed in Leopard:
http://developer.apple.com/releasenotes/Cocoa/AppKit.html
"NSTableView/NSOutlineView - Single click to editNSTableView and
NSOutlineView now behave like Finder and allow a single click to put
it into edit mode. This is done by calling -
hitTestForEvent:inRect:ofView: and checking if the cell returns
NSCellHitEditableTextArea. This allows you to set a doubleAction and
perform some different task when the doubleAction is invoked (for
instance, Finder opens files on a double click, and edits via a
single click). If the doubleAction is not set, editing is still
allowed via a double click."
The converse of this statement would be that, in 10.4.11,
doubleclicking will always edit.
Personally, I believe this should be explained in the current
documentation, but I've seen other cases in which Apple documents
version-specific behavior changes in Release Notes only. I don't
know if that is intentional Apple policy or a bug.
Please do log a bug requesting that we clarify this in the
documentation.
Nick -- the -doubleAction will work -- you just have to make sure the
cell isn't editable. If you do want to allow the text in it to be
edited, then you may be out of luck, since double click means "start
editing". There are ways around it, but it involves a bit of
subclassing and processing things differently depending on where the
user double clicks.
