Hi,
here is a fix for NSKeyValueCoding SetValueForKey() to prefer the
key as is (without leading underscore) before trying with underscore
(_key).
My problem: When loading a Nib file with a key named "infoPanel" for
NSApplication, the value gets set to "_infoPanel" instead, which
also exists in GNUstep.
I'm afraid your 'fix' is actually a request to introduce a bug. The
order in which things are searched for is well defined (see http://developer.apple.com/documentation/Cocoa/Conceptual/KeyValueCoding/Concepts/SearchImplementation.html)
and the GNUstep implementation needs to stick to that ordering. I
happen to think that the fact that KVC uses names with leading
underscores is a design error by Apple, but it's the way things are.
It seems to me that the problem is the choice of key or the choice of
ivar name, and any fix should be made at one of those rather than
changing the KVC mechanism.
