I am seeing this error when I load a window from a NIB. The error appears deep in Apple code. My loading code all executes correctly and when it is running all the outlets are set up correctly.
Cannot create BOOL from object <NSWindow: 0x7f883b44f770> of class NSWindow
Here is the code thats being called
- (void)awakeFromNib{
[self showLoginSheet];
}
- (void)showLoginSheet
// User has asked to see the custom display. Display it.
{
if (!self.loginSheet)
[NSBundle loadNibNamed:@"LoginSheet" owner:self];
//Check the myCustomSheet instance variable to make sure the custom sheet does not already exist
[NSApp beginSheet: self.loginSheet
modalForWindow: [[NSApp delegate] window]
modalDelegate: self
didEndSelector: NULL
contextInfo: NULL];
}
And the stacktrace is

As you can see from the stack trace, this seems to be nothing to do with my code. What am I doing wrong? I have no clue and the other answers to similar questions are not really helping.
It looks like one of your bindings is set up incorrectly in your XIB.
