macOS Hide/Show NSWindow?

[Aranince]

I'm trying to create a preference window, but I am having a problem bringing the window "back to life." When I first launch the program and open the pref window, it opens fine. I then close the pref window and try to open it again and no window pops up. How do I get the window to come back up after I close it? Here is how I open it in the first place through the window controller:

-(void)showPreferenceWindow:(id)sender
{
	[NSApp activateIgnoringOtherApps:YES];
	[[self window] center];
	[[self window] makeKeyAndOrderFront:nil];	
}

...and in the NSWindow subclass I just have

-(void)awakeFromNib
{
	[self setHidesOnDeactivate:NO];
	[self setReleasedWhenClosed:NO];
}

Are you sure awakeFromNib is being called? Is [self window] non-nil? Don't assume things are what you think they are. Use the debugger or logging

awakeFromNib is being called...[self window] is nil(assuming I'm checking it correctly: [self window] == nil ) and the window controller's init method is being called and succeeding.

My init method for the controller

-(id)init
{
	if((self = [super initWithWindowNibName:@"GHPreferences"]))
	{

	}
	return self;
}

Why would self window be nil? It's nil the first time I open the pref window...which I find strange. Does [self window] not exist until I call makeKeyAndOrderFront?

EDIT: I tried if([self isWindowLoaded] == NO) and the case is only true once.
