I have a billing application that I wrote a couple of years ago, and
I'm trying to get running again on 10.4. When I first opened the
project in Xcode 2.1, I received the warning (not unexpected) about
it being saved in an older version of Xcode and told it to upgrade a
copy. The project builds without any trouble, but when I try to run
it, I get the following in the Run Log:
An uncaught exception was raised
Cannot create number from object () of class NSCFArray
*** Uncaught exception: <NSInternalInconsistencyException> Cannot
create number from object () of class NSCFArray
App has exited due to signal 5 (SIGTRAP).
The run log also contained some NSLog() output that I had inserted in
[MyController init], but none of my other NSLog() output from other
methods, so I set a breakpoint at the end of init and ran the app
with the debugger. From the breakpoint, I started stepping forward
and found myself looping through loadNib. After several iterations,
I ended up with this list below under "Thread-1" in the Debugger window.
Any advice on how I can figure out where the problem is?
