[MacRuby-devel] My class's initialize not called

[Matt Aimonetti]

When reopening a Cocoa class, you should not overwrite initialize and if you
were to do it anyway, don't forget to call super and to return self.
The Cocoa way is to create your own initializer to end up with something
like DuplicateCounterTextField.alloc.initWithDuplicate

Also, remember that when initializing a Cocoa class, you need to do
DuplicateCounterTextField.alloc.init
