Awesome, thanks!
By the way - and this is a general question to anyone in the know - how
reasonable/feasible do you think it is to reimplement Carbon APIs on top
of Cocoa/GNUstep GUI?
I did some research of my own, but since I still lack the years of
experience in OS X development, I prefer to ask.
The bad thing about the state of OS X APIs is that people still haven't
let go of these now decades old Carbon & other APIs... I'm not talking
about reimplementing all of it, but rather the basic stuff to get
something working.

Now that the release is done I'm going to take another look at this.
I believe that if an NSCustomView is being encoded it should
probably be converted into an NSView when it is decoded by the nib
loader.
I believe that this change will solve your problem. I'm going to
make a change to GUI and send you a patch to see if that helps.
As an aside, I recall you suggested I test in Gorm. I have come to
a conclusion on this as well...
Flat nib files like this one can't currently be loaded in Gorm
because the loader doesn't have access to the metadata it needs to
determine custom classes and other information which is normally in
classes.nib and info.nib in older, pre XIB nib files.
The classes.nib and info.nib files both contain certain mappings
which are needed by Gorm to do the editing. Without them Gorm has no
way of knowing what the superclass of the custom class is. The
keyedobjects.nib file contains a pointer to the className of a custom
class, but it will not provide the super class of that class. This
is what the classes.nib file is for.
Because of this I don't think that Gorm will be able to edit newer
nib files beyond those created with 10.4/10.5, which is unfortunate.
So the course of action in Gorm should be to perfect XIB handling
in Gorm and also perfect the nib handling for the above mentioned
versions of Mac OS X.
All of that said, gui, since it doesn't require the same metadata
that Gorm does since the above mentioned files are only for editing,
should be able to load these files just fine once I've made my
changes.
I will report back here and post a patch for you to try.
Thanks, GC

Hi,
as part of my OS X loader, I'm not trying out various Cocoa apps,
one of them being Bayon.
https://itunes.apple.com/us/app/bayon/id532348700?mt=12 [1]
When starting the application under GNUstep/Linux, I get the
following error:
2012-11-06 12:57:34.728 Bayon[10234] NSView.m:4685 Assertion
failed in NSSplitView(instance), method initWithCoder:.

2012-11-06 12:57:34.730 Bayon[10234] BNMainWindowController: could
not load nib named BNMainWindowController.nib
The assertion in question is: [sub class] != [NSCustomView class]
The problematic .nib file is attached. For obvious reasons, I can
mail the whole commercial app here.
I can't absolutely rule out a bug in my loader (I do have unit
tests though), but Gorm not being able to load the file either
hints
at a possible bug in GNUstep.
Could someone in the know please quickly take a look at it?
Thanks a lot!
