Re: -stringValue on NSTextfield does not reflect actual contents [SOLVED]

A suggestion was made off list that I add a [title validateEditing] 
before requesting the text field's contents. This did the trick. As 
the docs say:

- (void)validateEditing
Validation sets the object value of the cell to the current contents 
of the cell’s editor (the NSText object used for editing), storing it 
as a simple NSString or an attributed string object based on the 
attributes of the editor.

For anyone else that comes across this problem, you must call this 
method before closing the window, as the field editor belongs to the 
window. I stuck it after the modal code but before ending the sheet:

   [NSApp beginSheet:sheetWin modalForWindow:[self window] 
modalDelegate: nil didEndSelector: nil contextInfo: nil];
   result = [NSApp runModalForWindow:sheetWin];
   
   [title validateEditing];
   
   [NSApp endSheet:sheetWin];
   [sheetWin close];

Thanks Justin!
