Possible Interface Builder bug with QCView in Leopard

A friend of mine was trying to embed a Quartz Composer composition into a Cocoa app, and he was having problems getting it to work properly. The composition responded to mouse events and it worked just fine within QC, but for some reason not within a QCView. I took a look at the project and he had done everything right, as far as I could tell; the "ForwardAllEvents" checkbox was checked. 

So, I decided to perform a little experiment. I added a view controller to the application with the QCView as an outlet.

Lo and behold, the eventForwardingMask was set to 1, not NSAnyEventMask as it should have been. The solution then presented itself: Set this value correctly in the -awakeFromNib and now the application worked properly

Here's the header file:

#import <cocoa/cocoa.h>
#import <quartzcomposer/qcview.h>

@interface MyViewController : NSObject {
  IBOutlet QCView *myView;
}

@end

And here's the implementation:

#import "MyViewController.h"

@implementation MyViewController

- (void)awakeFromNib
{
  NSLog(@"%d", [myView eventForwardingMask]);
  [myView setEventForwardingMask:NSAnyEventMask];
  NSLog(@"%d", [myView eventForwardingMask]);
}

@end

I'm going to file a bugreporter bug right away.
