Problem in creating new window in cocoa Mac on Button click

Question

I have two classes, firstView & secondView. In firstView.h

#import "SecondView.h"
#import "FirstView"


@interface FirstView : NSObject {

    IBOutlet NSButton *test;
    secondView *mySecond;
}

@property (nonatomic, retain) IBOutlet NSButton *test;


-(IBAction) buttonClicked:(id)sender;

@end

In firstView.m

#import "FirstView.h"


@implementation FirstView
@synthesize test;


-(IBAction) buttonClicked:(id)sender{

    NSLog(@"HELLO!!!");
    if (!mySecond) {
        // If the second view controller doesn't exist yet, make it!
        mySecond = [[secondView alloc] init];
    }
    [mySecond displayWindow]; 
}

@end

In secondView.h

#import 


@interface SecondView : NSObject {

    IBOutlet NSWindow *progressWindow;
    IBOutlet NSButton *testNew;
}

@property (nonatomic, retain) IBOutlet  NSButton *testNew;

- (void)displayWindow;

-(IBAction) buttonClickedNew:(id)sender;

@end

In secondView.m

#import "SecondView.h"


@implementation SecondView
@synthesize testNew;

- (id)init {

    if (self = [super init]) {
        NSLog(@"HAI!!");

        [NSBundle loadNibNamed:@"Next" owner:self];
    }
    return self;

}

- (void)displayWindow {

    if (![progressWindow isVisible]) {
        NSLog(@"ON SECOND!!!");
        [progressWindow setIsVisible:YES];
        [progressWindow orderFront:nil];        
    }

}

-(IBAction) buttonClickedNew:(id)sender {

    NSLog(@"GOOD!!!");
}

@end

But I am getting the output as....

There's a class for controlling windows in Cocoa: NSWindowController Why aren't you using it? Subclassing NSWindowController gets you all the nuts and bolts and then you just need to add in the methods specific to your use case. Much much simpler.

Also, it's not clear if these are separate windows or just separate views. If the latter, you'd want to investigate NSViewController
