I have a multi-window .nib file, and one of the windows is not
initially shown. My main controller has an IBOutlet that is hooked up
to the proper window. I also have another NSArrayController hooked up
to a table in the main window. I have these two lines in an IBAction
function with a button hooked up to it:
[AccountsController add:sender]; //AccountsController is my array
controller
[newAccountWindow makeKeyAndOrderFront:self]; //newAccountWindow is
the undisplayed window
Nothing else in the function, just these lines. The newAccountWindow
doesn't have anything bound, so it shouldn't matter what's going on
with the AccountsController. However, I get the following strange
errors in my Run Log in XCode:
2005-10-04 19:37:35.353 Finance[6819] *** -[JBAccount copyWithZone:]:
selector not recognized
2005-10-04 19:37:35.363 Finance[6819] *** -[JBAccount copyWithZone:]:
selector not recognized
*** malloc[6819]: Deallocation of a pointer not malloced: 0xbfffdfd0;
This could be a double free(), or free() called with the middle of an
allocated block; Try setting environment variable MallocHelp to see
tools to help debug
If I comment either one of these lines, the error goes away. I only
get the error when both of the lines are there.
Any ideas as to what might be causing this strange error? I'm quite
stumped.
Many thanks,
Josh
