Responding to myself (since nobody else did!), with additional
information...perhaps I didn't give enough info the first time.
As I said, I have a nib file that uses a custom palette for one of the
views. This custom view is used only in this one place, so the use of
the palette was overkill, and now that they are no longer supported,
it is a great PITA. I have deleted the widget, replaced it with a
standard CustomView (heh), rewired the connections, set the class to
the appropriate subclass, and things work just peachy.
But I cannot make the nib file understand that it no longer needs the
custom palette. After making the aforementioned changes (and on a
whim, I tried NOT setting the class of the widget to the appropriate
subclass, I simply left it as the standard view class--NSView) and
deleting the palette from /Developer/Palettes/, when I re-open the nib
file (in Tiger with IB 2.5.4), I get this error message:
"While opening "DocumentWindow.nib", the following error occured [sic]:
*** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of
class (MyControlSubclass)"
(I actually get this error message twice in a row opening a single
file.)
On Leopard, even though there is a /Developer/Palettes/ directory, and
even though my custom palette is in there, IB 3.x complains that it
cannot be opened because an instance of MyControlSubclass cannot be
decoded. Ensure all plug-ins used to created this document have been
loaded". Which is as I expected, but the directory name "/Developer/
Palettes" gave me a faint glimmer of hope.
I really would like to be able to open this file with having to reboot
into Tiger and run IB 2 to do it. As a last resort, I s'pose I could
recreate the entire nib file, but that would be non-trivial, tedious,
and extremely fraught with peril. Surely there has to be a better way
to exorcise this palette from the nib file.
Pretty please? :)

So I have this nib file from the Xcode 2.4/Interface Builder 2.5
days. My predecessor thought it would be a good idea to write an IB
palette for this view, which is used in exactly one place. Now that
IB palettes are obsolete, I now have to fix things.
I want to completely remove all traces of this palette, and simply
use the source for this view. I've opened the nib file in IB 2.5,
deleted the view that was created from the custom palette, created a
new view in its place and assigned it the appropriate subclass, and
rewired the connections. After having done that, I still cannot
open the nib file unless IB can find that custom palette. Needless
to say, this is going to be a problem moving forward to Leopard and
Xcode/IB 3.x.
What do I need do to rectify the situation?
