EncodeWithCoder: selector not recognized

Question

Hi all,
I want a class to conform to NSCoding for keyed archiving.
I implemented both methods
- (void)encodeWithCoder:(NSCoder *)encoder;
- (id)initWithCoder:(NSCoder *)decoder;
compiles without warning,
but on runtime the programm crashes with:
++2008-09-23 22:25:42.712 NSCodingTest[20876] * -[TestClass encodeWithCoder:]: selector not recognized [self = 0x34b9c0]+
++2008-09-23 22:25:42.730 NSCodingTest[20876] * -[TestClass encodeWithCoder:]: selector not recognized [self = 0x34b9c0]+
Anyone out there, who had the same problem or knows, what I am missing?
Here are the sample files:
TestClass.h:
#import <Cocoa/Cocoa.h>
@interface TestClass : NSObject <NSCoding> {
float testVar;
- (void)encodeWithCoder:(NSCoder *)encoder;
- (id)initWithCoder:(NSCoder *)decoder;
@end
testClass.m:
#import "TestClass.h"
@implementation TestClass
- (id) init {
self = [super init];
if (self != nil) {
testVar = 0.5;
return self;
- (void)encodeWithCoder:(NSCoder *)encoder {
if ([[super class] conformsToProtocol:@protocol(NSCoding)])
[super encodeWithCoder:encoder];
[encoder encodeFloat:testVar forKey:@"testVar"];
- (id)initWithCoder:(NSCoder *)decoder {
self = [super init];
if (self != nil) {
testVar = [decoder decodeFloatForKey:@"testVar"];
return self;
@end

was a weird typo that the compiler obcviously oversaw
