Hello,
I’m trying to use the NSBrowser class in a simple app. Everything works
find when the window opens and the NSBrowser display’s the array of
instances. But after I change the array of instances and send the NSBrowser
instance a “reloadColumnZero” message, I get an error about my class not
implementing ‘copyWithZone:’.
I can’t understand what is going on and why it things it doesn’t have that
method. It is defined up on NSObject as a class method. Now I’ve tried
making the domain class “SellItem” both a Ruby subclass as well as a
subclass of NSObject. Same error both ways.
Thanks for the help…
