I have about a year of experience with C++, but I am brand new to Objective C programming on Macs. I found a simple "Hello World" project at http://en.wikibooks.org/wiki/Programming_Mac_OS_X_with_Cocoa_for_beginners/First_Cocoa_program_-_Hello_World and decided to try it to make sure that Xcode was working. I followed all the directions, but when I hit "build and go", this message popped up in the run log:

[Session started at 2009-07-13 14:27:06 -0400.]
2009-07-13 14:27:06.600 HelloWorld[581] An uncaught exception was raised
2009-07-13 14:27:06.601 HelloWorld[581] *** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (WebView)
2009-07-13 14:27:06.601 HelloWorld[581] *** Uncaught exception: <NSInvalidUnarchiveOperationException> *** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (WebView)

HelloWorld has exited due to signal 5 (SIGTRAP).


Does anyone have any ideas as to what happened and how I can fix it? Thanks
