Hey Jens -
I would guess that that is where an exception is being re-raised. Do
you have a break point on just -[NSException raise]? Or do you have a
break point on objc_exception_throw? objc_exception_throw is the obj-c
exception throwing funnel on Leopard.
If you're able to get a backtrace from the real exception source,
perhaps I can give you better information about the cause of the
exception.

Hi,
I have created an IB 3.0 plugin that handles 3 of our custom classes.
For one of them, whenever I try to save a NIB in 2.x format, saving
fails with the following error written to the console:
2007-11-20 12:17:55.955 Interface Builder[65811:10b] ***
NSMapRemove(): attempt to remove notAKeyMarker
For the other two custom classes, saving works just fine. All of the
custom classes have an inspector palette, and I can't see anything
I'd be doing wrong.
In fact, for the class that fails to save to 2.x format, I can save
it to both 3.x NIB and XIB format, but just not to 2.x NIB format
(which is unfortunate, since we need to share this with Tiger
developers :( )
Also, when saving fails, my -[MyClass encodeWithCoder:] method is
not even called, the error appears to happen earlier.
The backtrace at the time the exception is raised is also not very
helpful to me - I have no idea which operation would trigger the
exception:
#0 0x917ecd86 in -[NSException raise] ()
#1 0x9441a5ab in -[NSCarbonMenuImpl
performActionWithHighlightingForItemAtIndex:] ()
#2 0x9441a1f2 in -[NSMenu performKeyEquivalent:] ()
#3 0x94418a99 in -[NSApplication _handleKeyEquivalent:] ()
#4 0x94335e4e in -[NSApplication sendEvent:] ()
#5 0x00004667 in ?? ()
#6 0x94293705 in -[NSApplication run] ()
#7 0x942609ba in NSApplicationMain ()
#8 0x00006cae in ?? ()
My code just doesn't seem to be involved with the save operation
itself, however, saving _only_ fails if an instance of this specific
custom view class is contained in the NIB...
I already tried removing all bindings from my inspector palette, in
case this causes the problem, but to no avail...
Since I have no further ideas what to look for - did anybody else
experience a similar problem and if so, what was the solution?
Any hints desperately welcome...
Thanks,
