Access Permissions for instances of a subform

Question

Is there any way to set access permissions for an instance of a subform rather than the subform as a whole? Especially for a template that has a certain number of instances saved, where only instances which have been previously saved should be access="nonInteractive" but new instances should be editable.

Like PeeJay says, a custom window controller seems the way to go. Try creating a subclass of NSWindowController, with header something like this:
#import <Cocoa/Cocoa.h>
@interface MyWindowController : NSWindowController
IBOutlet NSTextField *infoField;
-(void)setInfoText:(NSString *)str;
@end
The implementation of the setInfoText would be something like:
-(void)setInfoText:(NSString *)str{
[infoField setStringValue:str];
Create a nib file with your window in interface builder. Drop the header file for your custom window controller into the interface builder window. Set the custom class of the nib's File's Owner to MyWindowController. You can then hook up the window and infoField outlets from File's Owner to your window.
In the body of your code where you open a new info window, add something like:
MyWindowController *windowController=[[MyWindowController alloc] initWithWindowNibName:@"nameOfWindowNibFile"];
[windowController setInfoText:@"Whatever"];
[windowController showWindow:self];
If you are going to have an undetermined amount of these custom window, it might be a good idea to store the window controller instances in a mutable array, rather than retaining instance variables for each one.
