App crashes with "cannot decode object of class (WebView)"

Hi

I have a custom NSWindowController with a WebView IBOutlet in it and am getting this error when trying to open the window

-[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (WebView)

The web view is just a plain vanilla view dragged from the IB palette. In IB, I set the "filesOwner" to my custom NSWindowController class and connected the fileOwner to the web view.

Does anyone see where I messed up?

Thanks in advance

Ken

Here's the interface for my custom controller

@interface MyController : NSWindowController
{
	NSURLRequest		*request;
	
	IBOutlet WebView	*webView;
}


Here's the init method for the window controller

- (id) init { NSBundle *bundle = [NSBundle bundleForClass: [self class]]; NSString *path = [bundle pathForResource: @"WebPalette" ofType: @"nib"]; NSLog(@"nib path: %@", path); if (self = [super initWithWindowNibPath: path owner: self]) { NSURL *testURL = [NSURL URLWithString: @"http://www.apple.com/";]; NSLog(@"testURL: %@", testURL);

// app crashes right here but I suspect it's a delayed reaction from initWithWindowNibPath

		[self setShouldCascadeWindows: NO];
		[[self window] setFrameAutosaveName: @"WebPalette"];
		NSLog(@"About to show web view");
		[self show];
		
		NSLog(@"About to create NSURLRequest");
		request				= [[NSURLRequest alloc] initWithURL: testURL
											cachePolicy: NSURLRequestReloadIgnoringCacheData
											timeoutInterval: 60];
											
		NSLog(@"request: %@", request);
		
		[[webView mainFrame] loadRequest: request];
	}
	
	return self;
}

And here's the crash log
